It is difficult to claim that any system or program is completely secure. All of them may contain potential vulnerabilities - errors made during the development process - that can lead to serious consequences. Attackers often exploit such flaws. Information security companies continuously monitor vulnerabilities and update security databases. Their monitoring typically includes sources such as the U.S. Government’s National Vulnerability Database (NVD), security advisories, GitHub issue trackers, and open-source projects. To create malicious code, attackers use a variety of programming languages. Some are more popular in cybercriminal circles due to their ease of use, compatibility with specific systems, and the wide availability of libraries that help solve particular problems. The Most C…  ( 6 min )

The phrase “Click here” was once a cornerstone of internet navigation. It was ubiquitous across websites, often used as a direct instruction to users: simply click a link, button, or piece of text, and something new would unfold—whether it was a download, a page redirect, or a pop-up. In the early days of the internet, this phrase was essential, helping users navigate a relatively new and confusing online landscape. But today, “Click here” is seen as a relic, a remnant of simpler times that no longer meets the standards of modern web design and user expectations. In this article, we will examine how “Click here” came to prominence, why it has lost its relevance, and the evolution of web design that has led to the adoption of more sophisticated, user-centered alternatives. The Early Days of…  ( 8 min )

"Don't… just stand there in the corner; tell me so." That was the question that paralyzed me during a client meeting. I was certain of my code, proud of my GitHub, and active on LinkedIn.

Concurrency in Go Ismile Hossain ・ May 11 #go #programming #tutorial  ( 2 min )

❓ What is Concurrency? Concurrency is the ability of a program to manage multiple tasks at once. These tasks may not run exactly at the same time, but they are managed in such a way that it feels like they are happening simultaneously. Imagine you’re cooking dinner: You put water on the stove to boil. While the water heats up, you chop vegetables. Once it’s boiling, you add pasta. While pasta cooks, you prepare the sauce. You are switching between tasks. You're not doing everything at once, but you're switching between tasks efficiently to save time. That’s concurrency: smart multitasking, not true parallelism (which involves tasks running at the exact same time on multiple CPU cores) In Go, concurrency means: Your program runs multiple tasks (functions or processes). Each concurrent ta…  ( 19 min )

When you send a message over the internet—whether it’s a cat meme, a video stream, or a DNS lookup—it’s traveling through layers of protocols. Two of the most important transport-layer protocols in this stack are TCP and UDP. While TCP gets a lot of the spotlight thanks to its reliability and widespread use in web traffic, UDP (User Datagram Protocol) is the unsung hero behind many real-time and low-latency applications. In this post, we’ll demystify what UDP is, how it works, and why developers choose it despite its nickname: the "Unreliable Datagram Protocol." UDP is one of the core protocols of the Internet Protocol (IP) suite. It was introduced in 1980 as a lightweight alternative to TCP. UDP operates on top of IP and is used to send short messages called datagrams. The key difference?…  ( 4 min )

Understanding getHashCode() in C# When working with various controls or items in C#, particularly in Windows Phone 7 (WP7), you might encounter the getHashCode() method. This method is an integral part of the object class, allowing objects to produce a hash code, which is a sequence of numbers that computably represents the object. You may wonder if this hash code can uniquely identify an item like a picture or a song on your device. In this article, we will delve into what a hash code is and how getHashCode() works within the context of C#. What is a Hash Code? A hash code is a numerical value produced by a hash function, which maps data of arbitrary size to fixed-size values, usually for efficient data retrieval. It's a way to summarize data, which means that a unique piece of data may p…  ( 5 min )

前两天的文章内容对uniapp开发鸿蒙应用做了一些详细的介绍，包括配置开发环境和项目结构目录解读，今天我们正式开始写代码。 入门新的开发语言往往从Hello World开始，Uniapp的初始化项目中已经写好了一个简单的demo，这里就不再赘述，我们直接从布局开始说起。 Uniapp的布局方式和鸿蒙原生语言ArkTs有所不同，但又颇为神似。 幽蓝君之前总结过，所有的布局方式无非只有三种，横向、竖向和层叠，其他所有的布局方式都由这三种衍生而来，Uniapp也不例外。 ArkTs中有Row()、Column()、Stack()、Flex()这几个基础的布局容器组件，更复杂一些的还有像List()、Grid()、Scroll()等等。 而在Uniapp中，基础的布局方式我们通常直接使用view容器来实现。比如我想要实现一个横向的布局，使用view容器，在view的样式中设置布局方式为row： 而到了纵向布局，只需要把布局方向设置column就行了： 接下来比较难的部分到了，对于层叠布局，ArkTs直接提供了Stack()容器，并且有对应的对齐方式可以直接设置，比较简单。但是uniapp并没有提供这种对齐方式，flex-direction中是不能直接设置层叠布局的。 我们可以使用postion属性来实现。postion的作用是设置定位方式，有static、relative、fixed、absolute集中方式，我们今天要说的是absolute。 absolute是一种绝对定位方式，是脱离了文档流、相对于父元素的绝对定位方式。 更详细一点解释就是不管它有多少同级别的组件，都不影响它以父元素左上角为原点的定位，同样的它也不影响别人，相当于悬浮在上层，使用偏移量来控制位置。比如下面这段代码： 所以如果需要层叠布局的两个容器都使用absolute定位，并且使用top、left、bottom、right来设置对齐方式，就实现了鸿蒙中的Stack()一样的功能： 这里可以使用z-index来设置谁在上一层，另外，绝对定位的父容器需要设置position: relative属性，否则子组件无法找到目标。 以上就是Uniapp开发鸿蒙的基础布局方式，感谢您的阅读。  ( 3 min )

Introduction to BlockingCollection and Memory Management In C#, the BlockingCollection class is a powerful tool for handling producer/consumer scenarios in a thread-safe way. However, when dealing with large objects that can vary in size significantly—like the ones you mentioned ranging from 10 MB to 700 MB—it's crucial to manage memory effectively to avoid OutOfMemoryExceptions. To achieve this, we need a customized collection that extends the functionality of BlockingCollection by allowing us to limit the total memory used by the items stored in it. Understanding the WeighedBlockingCollection The goal here is to create a custom collection called WeighedBlockingCollection, which will not only mimic the behavior of BlockingCollection but also impose a weight restriction on the …  ( 5 min )

TypeScript offers powerful tools that help you write clean, scalable, and type-safe code. Two of the most useful features in this toolkit are Union Types and Type Aliases. In my latest YouTube video, I break down how to use these features effectively—even if you're just getting started with TypeScript. ✅ What You'll Learn ✅ What is a Union Type in TypeScript? ✅ How to use Union Types with function parameters ✅ What is a Type Alias and how to use it ✅ How to combine Union Types and Aliases ✅ Real-world use cases and code walkthroughs ✅ Common mistakes to avoid If you've ever found yourself repeating types or making your code harder to read, Union Types let you define a variable that accepts multiple types: let id: string | number; Meanwhile, Type Aliases allow you to give a custom name to a type: type ID = string | number; function printId(id: ID) { console.log("Your ID is:", id); } Combined, they make your code more readable, reusable, and easier to maintain. type SuccessResponse = { status: "success"; data: string; }; type ErrorResponse = { status: "error"; error: string; }; type APIResponse = SuccessResponse | ErrorResponse; function handleResponse(res: APIResponse) { if (res.status === "success") { console.log(res.data); } else { console.error(res.error); } } This is a clean, scalable way to handle multiple response types from an API. I walk you through all this and more in the full tutorial on YouTube: 👉 Watch on YouTube Whether you're building a small project or working with a large team, learning how to use Union Types and Type Aliases will make your TypeScript code more maintainable and developer-friendly.

Hello everyone! It’s been another productive month in the LFX Mentorship program with the CNCF Microcks project. This month, I focused on enhancing Microcks deployments on Google Kubernetes Engine (GKE) and improving documentation for cloud-specific deployment strategies. Additionally, I had the opportunity to present my contributions during the community meeting, where I encouraged others to contribute, provide feedback, and review the documentation. Asynchronous Options on GKE I worked on improving the Microcks GKE deployment by adding support for asynchronous protocols and securing the Microcks endpoint with TLS. Enabled Kafka-based async protocols with Helm and installed Strimzi for Kafka management. Secured the endpoint using cert-manager and Let's Encrypt for automatic SSL certificate provisioning. Deploying complex systems like Microcks with external Keycloak and MongoDB can sometimes lead to roadblocks. To address this, I created a TROUBLESHOOTING.md file in the repository. This document provides a set of common issues and solutions that developers may encounter when deploying Microcks on GKE, especially when integrating with Keycloak for authentication and MongoDB for data storage. Troubleshooting Guide I developed a GUIDELINES.md document that outlines the deployment process for Microcks across multiple cloud providers. The guidelines cover setting up infrastructure, deploying Keycloak, provisioning databases, and configuring Microcks with Helm. Common Guidelines Next month, I plan to: Deploy Microcks on Azure AKS and document the process. Add a Troubleshooting Guide for Azure deployment. Month two has been an exciting journey, contributing to Microcks with improvements in deployment, security, and cloud-specific guidelines. I’m excited to continue supporting the Microcks community and look forward to the next steps!

It's one of the most widely used formats in web development, especially when working with APIs and server responses. JSON is a text-based format for representing structured data. It resembles JavaScript object syntax, but it's a string. Example JSON: { "name": "Alice", "age": 25, "isStudent": false, "skills": ["HTML", "CSS", "JavaScript"] } They look similar, but they are different: Feature JavaScript Object JSON Data Type Object String Can contain functions Yes No Comments Allowed Not allowed Quotes on keys Optional Mandatory JSON.stringify() Converts a JavaScript object into a JSON string. const user = { name: "Bob", age: 30 }; const jsonString = JSON.stringify(user); console.log(jsonString); // '{"name":"Bob","age":30}' JSON.parse() Converts a JSON string back into a JavaScript object. const jsonString = '{"name":"Bob","age":30}'; const user = JSON.parse(jsonString); console.log(user.name); // 'Bob' fetch('https://api.example.com/data') .then(response => response.json()) .then(data => { console.log(data); // Parsed JSON object }); Most APIs return JSON. Using .json() parses the response body into a JavaScript object. Forgetting to wrap keys in quotes in JSON: { name: "John" } // Invalid Correct: { "name": "John" } Using functions in JSON: JSON.stringify({ sayHi: () => "Hi" }); // sayHi will be removed JSON is used for storing and exchanging data. Use JSON.stringify() to convert objects to strings. Use JSON.parse() to convert strings to objects. It’s widely used in API communication. Tip: Use https://jsonformatter.org/ to format or validate JSON quickly.  ( 4 min )

Clean Architecture is a great concept. It’s meant to help you write maintainable, modular, and scalable software. But too many developers treat it like a religion. They follow it blindly, stuffing projects with unnecessary layers, abstractions, and patterns. All in the name of “clean code.” Let’s be honest, Clean Architecture is often overused, not because the ideas are bad, but because people overengineer the implementation. Here’s an example of multiplying two numbers implemented with an absurd number of patterns: // overengineered-multiplier.ts // Interface interface IMultiplier { multiply(a: number, b: number): number; } // Singleton class MultiplierService implements IMultiplier { private static instance: MultiplierService; private constructor() {} static getInstance(): Mu…  ( 5 min )

The attacker deployed the contract from address 0xb32a53... at 07:31:38 UTC and initiated the exploit at 07:33:56 UTC, draining funds from the victim wallet 0xb5252f... Cyvers confirmed to Cointelegraph that the attacker used contract 0x631adf... to execute a series of malicious transactions. The smart contract drained 28.5 million MBU tokens and converted them into stablecoins, resulting in a net loss of $2,152,219.99 for the victim. In total, the attacker stole 28.5 million MBU tokens and converted them to $2.15 million worth of USDT. Cyvers labeled the exploit as “critical” and noted the attacker’s use of suspicious contract code and abnormal transaction patterns. The attacker’s wallet remains active and has retained the stolen funds as of publication. Mobius Token’s team has not yet released an official statement. “Two minutes prior to the exploit, our system identified a deployment of a malicious smart contract that eventually targeted the Mobius Token smart contracts,” Cyvers wrote on X.

Altcoin markets are flashing early signs of a breakout, with several analysts calling for a potential surge over the next few months. Crypto commentator Mister Crypto predicts the next 3 to 6 months could be “life-changing,” suggesting daily gains of up to 40% may soon become the norm. In a May 11 post on X, he pointed to a chart from BlockchainCenter.net that shows whether the crypto market favors Bitcoin (BTC) or altcoins. When the index is below 25, it’s considered “Bitcoin Season,” meaning Bitcoin is outperforming most altcoins. When it’s above 75, it’s “Altcoin Season,” meaning altcoins are doing better than Bitcoin. Currently, the chart shows a breakout from a downward trend just below the 29 mark, suggesting a possible shift away from Bitcoin dominance. This breakout hints that altc…

Coinbase CEO Brian Armstrong said his company had considered adopting a Bitcoin investment playbook like Michael Saylor’s Strategy on multiple occasions, but decided against it each time out of fear that it would kill the firm’s crypto exchange, Bloomberg reported. “There were definitely moments over the last 12 years where we thought, man, should we put 80% of our balance sheet into crypto — into Bitcoin specifically,” Armstrong revealed to Bloomberg in a May 9 video call. Armstrong said the Bitcoin (BTC) strategy could have risked the company’s cash position and potentially killed the crypto exchange. “We made a conscious choice about risk,” he added. Coinbase Chief Financial Officer Alesia Haas, who also attended the video call, added that the firm didn’t want to be seen as directly com…

Abstract Introduction The conventional model of web application development separates frontend and backend responsibilities into different teams, skillsets, and codebases. Frontend developers manage UI and client-side logic, while backend developers handle server-side processing, API creation, data storage, and security enforcement. However, this division can lead to longer development cycles, coordination challenges, and duplicated logic across layers. A new paradigm is emerging—one in which frontend developers can declaratively define backend logic using frontend tools and syntax. This shift is enabled by modern platforms that offer serverless scalability, secure permission management, and efficient request/response handling under the hood. This approach doesn't eliminate the need for ba…  ( 5 min )

Introduction to UDF and Vector UDF in Spark 3 In Spark 3, the advent of vectorized UDFs (User Defined Functions) has created a significant advancement in how operations on DataFrames can be efficiently executed. Understanding the differences between traditional UDFs and the newer vectorized UDFs is crucial for optimizing performance in big data processing. What are User Defined Functions (UDFs)? Traditional UDFs User Defined Functions, commonly referred to as UDFs, are functions written by users to extend the functionality of Spark. They allow you to perform custom operations on DataFrames and Datasets. For example, if you want to apply a complex transformation that is not available out-of-the-box in Spark, a UDF can be created in languages like Scala or Python.

Introduction When working with Entity Framework Core (EF Core) in C#, managing relationships between entities is crucial. In this scenario, we have a case where a department can have multiple users, and when a user is assigned a new department, we need to ensure the previous department is deleted if it has no users left. This is a common requirement in applications that handle organizational structures. Why the Department Query Might Not Reflect Updates In your situation, you are attempting to update a user's department and then immediately check if the previous department has users left. You notice that even though the update reflects in the database, the department load returns stale data. This issue can arise due to EF Core’s change tracking behavior and how it interacts with the databa…  ( 5 min )

Libuv describes itself as a multi-platform support library with a focus on asynchronous I/O. It is widely used in many web servers (e.g., Kestrel) and runtimes such as Node.js and Python (via uvloop). As of Zig 0.14.0, there is no native async I/O, so you must work directly with threads or create your own async API using OS primitives like epoll or kqueue. In many cases, you would likely choose a cross-platform library rather than implementing your own async API. That’s where using libuv, libevent, or libxev (written in Zig) becomes useful. This guide will show you how to use libuv from your Zig project. I’ll start with a basic Zig project to demonstrate how this works. It will be a simple app that runs some timers. We’re going to use the package from github.com/allyourcodebase/libuv to bu…  ( 5 min )

An open-source project called Deep-Live-Cam is gaining traction on GitHub — and for good reason. With just a single still image, it can mimic anyone’s face in a live video call. In real-time. Running locally. No cloud required. The implication is clear: you can no longer trust a video call at face value. So here’s the question: how do we verify identity in a world where faces can be forged on demand? While many react with fear or disbelief, I see only one viable answer: digital signatures. For years, I’ve been saying: we should encrypt everything — files, messages, infrastructure. But now, that’s not enough. We need to start signing everything. Digital signatures ensure authenticity. They prove that something really came from who claims to have sent it and hasn’t been tampered with. We already sign emails, source code, and software packages. Why not apply the same principle to real-time streams? Imagine a video call cryptographically signed with the speaker’s GPG key. Even if the face looks convincing, if the signature doesn’t verify, you know something’s off. I sign every HTML page on my personal website with my GPG key. Not because I’m paranoid — but because I believe security should be a mindset. Don’t trust. Verify.  ( 3 min )

Introduction In modern web applications, displaying real-time data is crucial, especially for user engagement. In this article, we'll explore how to effectively update a progress bar within a table using the MantineReactTable component in a React application. The focus is on integrating WebSockets to receive progress updates without causing unnecessary re-renders. Understanding the Challenge You might be facing an issue where your progress bar component does not rerender despite the state updates from useState. This can be confusing, especially when the console confirms that the state is updating. The problem often resides in how Reac's reconciliation process manages component updates and how state is propagated to child components. Setting Up the WebSocket Connection To facilitate real-ti…  ( 5 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line I built a CLI tool in Go that automates safe dependency upgrades in Go projects using Amazon Q Developer. The tool addresses the common pain point of manually updating dependencies, which is often error-prone and time-consuming due to compatibility issues. Here's what it does: Auto-scans Go projects for outdated dependencies Uses Amazon Q to generate AI-powered compatibility reports Predicts potential code conflicts before upgrading Automatically applies safe upgrades, runs tests, and opens a GitHub PR The tool streamlines the entire upgrade pipeline while integrating AI-powered risk analysis before making any changes — something that's often missing in conventional dependency managers Demo Flow: Run the CLI: ./q-dep-updater -path=~/dev/myproject -repo=me/myproject See predicted conflicts before upgrades PR automatically created once tests pass 🔗 GitHub Repository – cli-rules Amazon Q Developer was the intelligence behind this tool. I used the q chat CLI interface to: Scan the project and extract outdated dependencies in structured JSON Predict compatibility conflicts based on code patterns and version diffs Generate a compatibility report with AI-based suggestions for refactoring By integrating Amazon Q directly into the upgrade workflow, I was able to: Detect breaking changes before installation Avoid unnecessary manual debugging Ensure only conflict-free upgrades move forward Tip: I found Amazon Q Developer's ability to contextualize Go code very effective when fed with detailed prompts about version differences. Using structured output like JSON made it easy to integrate with the CLI logic.  ( 3 min )

If you're learning C# or .NET development, you might encounter this frustrating error: One or more errors were encountered while creating project ConsoleApp3. The generated project content may be incomplete. The SDK 'Microsoft.NET.Sdk' specified could not be found. I faced exactly this issue during my early days learning C#. After multiple attempts, I finally found a solution that worked reliably for me: The root cause appears to be that the official .NET SDK installer sometimes doesn't correctly set up the SDK on your system. Even after installation, the command dotnet --list-sdks might return an empty list, which indicates the SDK isn't properly recognized by your system. Here's what worked for me: Download the Binaries Manually: Go to the official .NET SDK downloads page. Instead of downloading the installer, choose the "Binaries" option. This will give you a .zip file containing the SDK files directly. Extract and Copy Files: Extract the downloaded .zip file to a temporary location. Replace SDK Contents: Navigate to: C:\Program Files (x86)\dotnet\ Delete or back up existing contents, then paste the newly extracted SDK binaries into this folder. Verify Installation: Open a new Command Prompt or PowerShell window and run: dotnet --info You should now see details about the SDK and runtime versions installed. This solution manually ensures that the SDK files are correctly placed and recognised by your system, bypassing the potential issues caused by the automated installer. If you're still experiencing issues after following these steps, consider checking your environment variables to ensure C:\Program Files (x86)\dotnet\ is correctly listed in your system PATH. I hope this guide helps anyone stuck with this annoying issue! If you find additional solutions or improvements, please share them—I'm still learning and would love to hear from you.  ( 3 min )

gRPC (Google Remote Procedure Call) is a high-performance, open-source framework for making remote procedure calls. Unlike traditional REST APIs that use HTTP/1.1 and JSON, gRPC leverages HTTP/2 and Protocol Buffers for more efficient communication between distributed systems. This modern approach offers significant advantages in terms of performance, type safety, and code generation capabilities. When working with gRPC, you need to understand the fundamental components and workflow that differentiate it from other API communication methods. The process begins with defining your service interface using Protocol Buffers (protobuf) in a proto file, which serves as a contract between client and server. This definition is then compiled into language-specific code that handles all the underlyin…  ( 5 min )

Introduction Have you ever faced an unexpected behavior in your Bash scripts, particularly regarding loops? In this article, we will delve into a common issue with the continue statement in Bash, as illustrated by your provided script. You're correct in observing that the continue statement should skip the remaining commands in the loop and jump to the next iteration. So, why isn’t it working as expected in your case? Understanding the Issue The primary reason the continue statement may not be functioning as you expected lies in the structure of your loop and the way Bash interprets commands. A common mistake is how command substitutions and pipes are handled in Bash scripts. When you use a pipe (|), the commands are run in separate subshells. This means the continue statement is scoped to…  ( 4 min )

As software engineers, our job isn't just writing features or fixing bugs. We're responsible for improving the processes around software and help teams move faster, safer, and more consistently. That means asking questions like: Can we reduce repetitive tasks? Can we encode best practices so new team members don't guess? Can we lower the mental load of starting new features? For Angular projects, Schematics is one of the best tools to operationalize these improvements. It lets you automate architecture, encode standards, and enforce patterns. A schematic in Angular is a set of instructions that tells the Angular CLI how to generate or transform code. Think of it as a script that can: Create new files using templates. Update existing code (e.g. add a component to a module). Enforce consiste…  ( 4 min )

When writing end-to-end tests with Cypress, you must often validate that your application sends or receives the correct data. Cypress’s cy.intercept() gives you robust control over network requests. However, digging through nested bodies, headers, and query parameters to find the exact key/value you care about can become repetitive and error-prone. That’s why I created cypress-intercept-search, a small plugin that lets you recursively search through every part of one or more intercepted requests or responses for a given key and (optionally) a matching value. Then, wrap the results in a chainable Cypress command for easy assertions. ## Why Built cypress-intercept-search cy.wait('@savePlay').then((i) => { const { players } = i.request.body; expect(players).to.exist; Object.entries(play…  ( 4 min )

Many years ago, I came across a profile on Twitter, now X, doing amazing things in development, and I was intrigued and wanted to get close to this person. I sent a couple of messages just to catch his attention, and when I asked him to be my mentor, he ghosted me. I felt so bad, like it hurt, but many years later, I understood. Because you feel he inspires you, it does not mean he/she is the right person to guide your growth. Mentorship has long been the cornerstone of personal and professional growth, especially in tech. Yet, in 2025, finding the right mentor remains one of the most elusive achievements for young professionals. It’s not just about guidance, it’s about survival in a fast-moving industry where knowledge gaps can determine one’s relevance. In this article, we unpack why…  ( 6 min )

Introduction In web design, ensuring that images maintain their size when a user resizes their browser can be crucial. Many developers face challenges in retaining the original dimensions of images while still creating a responsive layout. If you've encountered similar frustrations—like trying to prevent an image from resizing, despite applying various styles—you're not alone. This guide will help you understand how to achieve this. Why Images Resize in a Responsive Layout Images typically resize in a responsive layout owing to CSS settings such as width, max-width, and other stylesheet rules. By default, images are treated as inline elements, and their sizing depends on the surrounding container. When modifying the browser window, the layout recalibrates, and unless the styles are explici…  ( 4 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: That's Entertainment! My inspiration for this project is threefold: the classic PC game, Pong, Pickleball and the 80s sci-fi movie TRON. I wanted to combine the two games into one – using pickleball paddles and a pickleball ball as the main interactive elements and the gameplay of Pong. Finally, TRON is my inspiration for the UI. I favor Visual Studio Code in my workflow, so I used Amazon Q Developer within Visual Studio Code as a chat buddy. I am letting Amazon Q Developer handle all the coding while I stepped into the director role, sipped my coffee and instructed the AI developer along the way.

This post explains why and how I use GitHub for nearly everything. I will also explain how I use GitHub Actions to automate the creation of issues in my GitHub Projects. I am using GitHub for both personal and work projects. In the past, I used BitBucket, and at some point I considered using GitLab, too. However, the popularity of GitHub and its ecosystem made it hard to ignore. I even use GitHub to follow trends in my profession. So, I doubled down on GitHub and started using it for everything. Probably the most important feature my team and I use is GitHub Projects. I dropped all other project management tools and even my lifelong quest for the perfect project management tool in favor of adopting GitHub Projects. I am not a fan of the GitHub UI.

In Go, when you have multiple struct types that need to perform the same methods, it can often lead to code duplication. This issue is quite common, especially in cases where you have several struct types with similar methods. In this article, we will explore how to effectively reduce method duplication using interfaces and composition, thereby making your code cleaner and more maintainable. Understanding the Problem Let's begin by analyzing the problem you've presented. You have several structs (A, B, C, and D) that all implement the same methods, specifically Add and Remove. Repetition of code leads to maintenance challenges—any change in method logic must be mirrored across all structs, increasing the risk of errors.

Photo by Taylor Vick on Unsplash Deploying applications on AWS Elastic Beanstalk simplifies many aspects of running your web applications, but setting up SSL/TLS on single-instance environments can get a bit tricky. In this article, we’ll explore two practical approaches to implementing SSL for your Elastic Beanstalk single instances. AWS Elastic Beanstalk single instances don’t come with built-in SSL termination like their load-balanced counterparts. When you deploy a web application in a single-instance environment, you’re essentially working with a standalone EC2 instance without the benefits of an Application Load Balancer to handle SSL termination. However, there are compelling reasons to use single instances: Cost efficiency : Avoiding load balancer costs for smaller applications Sim…  ( 6 min )

This blog is for those, who want to start their first full stack development project but not have enough idea about how to start. I will try to cover some of the things that you should follow for make your first project journey more smooth. Folder Structure: The first thing you might face difficulties is creating and understand the folder structure. It may vary by project to project, but their are some common concept like creating 2 separate folder, one for frontend and other one is for backend. Inside each folder you will have multiple folders. For backend you will have folders like models, services, api endpoints etc (based on your requirements) . And for frontend, you will have src folder inside which you will find components, assets, pages, api, utils etc folders (if you are using React). fullstack-project/ Make sure you must write code as clean as possible. It is a good practice. You should right the logics more efficient way. You can also create a folder for a particular module and inside that you can create multiple files so that anyone can easily find the code written for a specific purpose. It will reduce cognitive complexity. Another thing you should remember that don't make a function so large with so much logics in a single function, rather use multiple functions, each for a particular logic and use them in that function. Before writing any routes, you should always first do some floor planning like how this routes is going to use, how many times this routes will be called. It is completely necessary when you are going to deploying the project into the server. Because the more api needs to call from backend, the more it will take time to load and resulting the website slow. Wish a happy journey for your first project 😄 and share if you find this post helpful.  ( 4 min )

Have you ever felt like you're fighting with your own APIs? As a backend developer, I sure did... until I learned to stop debugging through the frontend and start talking directly to my APIs instead. Last month, I was building a backend for a mocktail ordering system. Everything was in place: // Our beautiful API endpoints app.post('/api/auth/register', registerUser); app.get('/api/auth/logout', logoutUser); app.get('/api/products', getProducts); app.post('/api/events', createEvent); app.post('/api/orders', createOrder); app.get('/api/invoices', getInvoices); app.get('/api/payments/history', getPaymentHistory); app.delete('/api/users/:id', deleteUser); Then the moment of truth came: testing the "Delete Account" feature.

Most programmers will agree that state management is a pain (in the head). Which is why they shy away from it at every opportunity. Languages, functional or OOP, make no difference - if state is only ever passed around to and from the database, it's all practically stateless in my book. In the industry-accepted programming model (clean model, layered model, hexagonal model) state management (database I/O) is on the outer layer - why? Oh, because you don't actually operate on entities that you store, you operate on transient entities derived from them. This abstraction is necessary, because in most modern languages state is carried by objects - and you can't store objects, only things derived from them. Be it rows in tables, or at least whole aggregates in NoSQL DBs. Actual object state can…  ( 4 min )

At M47 Labs, we work on many AI and cloud-native projects where secret management becomes complex — especially across environments and CI/CD pipelines. We're big fans of AWS SSM for storing configuration and secrets securely, but syncing them into .env files can be painful and repetitive. To solve this in a cleaner and more reliable way, I built a CLI tool: 👉 Envilder on GitHub Envilder reads a mapping file that links environment variable names to AWS SSM parameter paths. .env file. Your param-map.json might look like this: { "DB_HOST": "/my-app/dev/DB_HOST", "DB_PASSWORD": "/my-app/dev/DB_PASSWORD" } Run: envilder --map=param-map.json --envfile=.env And you get: DB_HOST=mydb.cluster-xyz.rds.amazonaws.com DB_PASSWORD=supersecret You can also use different AWS CLI profiles: AWS_PROFILE=staging envilder --map=param-map.json --envfile=.env This small tool makes a big difference when: 🧑‍💻 Onboarding new team members: no more “what’s the DB password?” 🔄 Keeping environments in sync: any change in SSM is reflected across the team ⚙️ CI/CD pipelines always up-to-date: e.g. GitHub Actions, CodeBuild, GitLab 🧼 Centralized configuration: avoid duplication and keep secrets in one secure place 🧭 Supports multiple AWS profiles: ideal for multi-account or multi-env setups Works with SecureString and plain parameters CLI-first, fast, and script-friendly Compatible with any CI system Supports static values and fallbacks AWS profile support (AWS_PROFILE) npm install -g envilder Or: envilder --map=param-map.json --envfile=.env --profile=aws-account It’s still an early-stage project, but already helpful in several real-world teams.

Stop Guessing: Understand JavaScript Equality the Right Way When you start working with JavaScript, one of the first things you notice is how flexible it feels. You can assign different types of values to the same variable and JavaScript won’t complain. This flexibility is great—but it can also lead to unexpected bugs, especially when you're comparing values or checking if something is "true" or "false." Let’s break down some of these concepts in a beginner-friendly way so you can write safer and more predictable JavaScript code. In JavaScript, you don’t need to declare the type of a variable. For example: let x = 5; // x is a number x = "hello"; // now x is a string x = true; // now x is a boolean This is called loose typing—a variable can hold any type of data, and JavaS…  ( 6 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Crushing the Command Line Some AI-powered coding assistants already support code reviews, but most of them tend to review an entire workspace or just the currently open file. In real-world scenarios though, code reviews are often based on pull requests—where we only need to review changes between two branches, not the whole project. For example, reviewing just the differences between a hotfix branch and main. That got me thinking: wouldn’t it be great if an AI coding assistant could handle that kind of focused review? At least as a first layer—giving us a detailed AI-generated review of the changes before we jump in manually. That way, human reviewers can just focus on refining things further instead of starting from scratch. One of Amazon Q Developer’s cool features is its CLI and MCP (Model Context Protocol) support. So I thought: why not use Amazon Q CLI to compare two branches—say, hotfix and main—and then have it go through the changed files one by one, review them, and finally compile the feedback into a single file using MCP as well? That way, whoever’s reviewing the PR can read the AI’s review first before doing their manual checks. Code Repository Code Review with Amazon Q Developer CLI I used Amazon Q Developer as the first layer of code review—comparing one branch to another, like from hotfix to main. This helps make the review process smoother, more effective, and scalable—especially when combined with a follow-up manual review. What makes it even more exciting is that Amazon Q Developer can both generate code and review it too. Pretty handy, right?  ( 4 min )

-- Loose Equality allows different kinds to become an equal kind. I've been feeling, blogposts treat loose equality in JavaScript as a kind of black magic because people do not master it.

When working with MySQL databases in PHP, you might run into scenarios where you desire to sort your data permanently. You mentioned trying to use the ALTER TABLE statement along with an ORDER BY clause, but this combination does not provide the desired outcome. In this article, we will guide you through the proper methodology to ensure your database records are sorted permanently and can be retrieved in the desired order. Understanding the Requirements for Sorting Sorting a database table involves arranging the records based on certain criteria—such as alphabetically or numerically—using specific columns. However, the ALTER TABLE command does not utilize the ORDER BY clause for sorting data. Instead, the sorting of records is meant to be performed during data retrieval using the SELECT st…  ( 5 min )

So this week, I tried to share what I’m building on Reddit. Two posts. Two different subreddits. Both were removed instantly by Reddit’s filters. No explanation. No mod feedback. Just gone. What were the posts about? I’m building a solo project called KindredCircl — a social platform focused on belonging, privacy, and connection. No ads. No rage-bait. No surveillance. Both posts were written thoughtfully. No spam. No “buy this.” Just honesty, tech stack, and a link to a longer write-up on Dev.to. But apparently, Reddit’s automation saw all that and said: nope. Reddit is supposed to be where indie hackers hang out. Where devs build in public. Where creators share early work and get support. But what I’m realizing is: if your post doesn’t match the format the filter expects, or if you use certain words (like support, link, or solo founder), you might just get silenced. Not because of what you said — but because a bot decided you were promotional by default. I’m still building. I’m still sharing. But I’m reminded how important it is to build spaces where authentic effort isn’t treated like spam. KindredCircl is meant to be one of those spaces. And yes — it still exists, even if Reddit didn’t want to hear about it this week. If you’ve had posts removed without explanation, or felt like you’re shouting into the void, I’d love to hear your story too. Let’s be loud for each other — since these platforms clearly won’t do it for us.  ( 3 min )

A few days ago, I stumbled across an interesting blog post by Solusipse about hiding images in sound—more specifically, encoding them into the spectrogram of an audio file. It reminded me of old-school tech like dial-up modems and the ZX Spectrum, but with a modern twist. Naturally, I had to try it. Solusipse provides a Python script, spectrology.py, that takes an image and converts it into an audio waveform whose spectrogram visually resembles the image. I cloned the repo, followed the README, and ran the script, hoping for a cool output. But things weren’t so smooth. The script hit an error out of the gate. Can't blame them, the code was over 10 years old 💀. After a not-so-long debugging session, I got it working. It finally produced an audio file containing a hidden image. Success—sort…  ( 4 min )

As a beginner in SQL, encountering syntax errors can be frustrating, particularly when you're trying to retrieve a set of random rows multiple times from a database. The query you've shared is an attempt to use a Common Table Expression (CTE) with recursion to select rows from the 'transaction_detail' table. However, it appears there are a few syntax issues that need to be addressed. Understanding the Query Structure The objective of your SQL query is to generate a recursive CTE that selects a specific number of rows (in this case, 6) from the 'transaction_detail' table where the 'company_id' matches 12345. In the initial part of the CTE, you're correctly selecting the first row matching the condition. However, there are syntax errors that lead to the error message you've received. Common …  ( 4 min )

Introduction: Welcome to Prompt Land Imagine you're handed a genie that can code, write, and brainstorm anything for you – but with a catch. This genie is very literal. Wish for "a game," and you might end up with a simple tic-tac-toe when you wanted a fantasy RPG. Ask it to "tell me about dogs," and it could ramble aimlessly about canines. To get useful results, you must phrase your wishes just right. In the world of AI, this art of wording your requests is called prompt engineering. But fear not, brave adventurer – prompt engineering isn't as arcane as it sounds. Think of it as giving instructions to a very smart but overly literal friend. If you're clear and specific, you'll get spectacular results; if you're vague, you might get something hilariously off-base. So, how do we craft the…  ( 6 min )

Amazon Web Services (AWS) has just announced a powerful enhancement for Amazon Elastic Block Store (EBS): Provisioned Rate for Volume Initialization is now generally available. This new feature allows you to create fully performant EBS volumes from snapshots with predictable initialization speeds, helping you launch EC2 instances faster at scale. It’s a game-changer for high-performance, time-sensitive workloads. 🧠 The Problem (Before This Feature) When launching EC2 instances from EBS snapshots (like AMIs), volumes are lazy-loaded from Amazon S3. That means data is only fetched when accessed for the first time. This causes: Slower disk I/O initially Inconsistent application performance Delays in workload readiness This has long been a pain point, especially for workloads tha…  ( 4 min )

It all started innocently enough. Back in 2009, I just wanted to port Earcut to Flash for a mini-game I was working on. And honestly? It worked — for a while. But over time, I realized that simple solutions tend to fall apart the moment you try to push them to their limits. That’s when I dove into the theory - digging through research papers, YouTube tutorials, and whatever else I could find. One of the most helpful resources was a book by A.V. Skvortsov. Eventually, I landed on the classic approach: decomposing a polygon into monotone pieces. It seemed obvious. And oh - I hit every possible wall while trying to make it work. The first big insight? Replace float with int. That alone got me almost there. But the algorithm was still fragile. Really fragile. Self-intersections, collinear edge…  ( 7 min )

Docker isn’t just about running containers. It’s about understanding how systems work, why things break, and what to do next. Most tutorials give you commands to copy paste.

✍️ Introduction Throughout my experience working with clients from domains like healthcare, insurance, and legal, I often found myself curious about how certain backend document workflows functioned, especially in healthcare. While supporting these systems, I’d often get paged for incidents related to PDF pipelines: upload failures, script errors, or extraction gaps. At that stage, like many in support roles, we’re limited to handling outcomes rather than building or understanding the full solution. Over time, as we gain more experience, build trust, and make people feel confident in our abilities, we gradually get the opportunity to be part of architecture discussions and solution design conversations. But that curiosity about how these pipelines actually work — from PDF upload to raw t…  ( 5 min )

That lack of interoperability is a major blocker to scaling truly useful, distributed AI systems. That’s where the Agent2Agent Protocol (A2A) steps in—and if you're a developer, now is the time to start paying attention. 🧠 What Is the A2A Protocol? It defines a standard interface for task negotiation, capability discovery, status updates, and result delivery between age…  ( 4 min )

Kubernetes is the go-to tool for managing containerized apps. While Services expose apps, they lack advanced traffic control. Ingress fills this gap with features like path-based routing, SSL, and load balancing. In this tutorial, we’ll explore Ingress and build a hands-on project using Go, Docker, and Kubernetes. In Kubernetes, Ingress is an API object that manages external access to services, typically for HTTP/HTTPS traffic.

What is QitOps? QitOps is a command-line tool for software testing — built to unify API, performance, security, and web testing workflows into a single, Rust-powered CLI. If you've ever juggled Postman collections, k6 scripts, custom curl chains, or browser test wrappers, QitOps is meant to replace that chaos with a clean, structured, extensible CLI. As someone who’s worked in QA and dev automation for nearly two decades, I’ve seen the testing ecosystem get increasingly fragmented. We use one tool for APIs, another for performance, yet another for security... then we stitch them together with shell scripts and cross our fingers. I wanted a tool that: Runs everywhere (local, CI, offline) Has zero GUI dependency Uses JSON/YAML for clean, repeatable test configs Works for QA engineers and D…  ( 4 min )

Pandas is a panda package for data manipulation and visualization. Pandas is built ontop of Numpy and Matlplotlib(data visualization). In pandas, data analysis is done on rectangular data which is represented as dataframes, in SQL they are referred to as tables. Returns first few rows of the dataframe print(alcohol_df.head()) To get the names of columns, and their data types and if they contain missing values print(alcohol_df.info()) To get the number of rows and columns of the datframe displayed as a tuple. This is an attribute, not a method. print(alcohol_df.shape) To get the summary statistics of the dataframe; print(alcohol_df.describe()) To get the values in a 2D NumPy array print(alcohol_df.values) To get the column names print(alcohol_df.columns) To get row numbers/row names print(alcohol_df.index) Change order of the rows by sorting them using a particular column. This automatically sorts be ascending order, from smallest to the largest. sorted_drinks = alcohol_df.sort_values("region") print(sorted_drinks) To sort by descending order sorted_drinks = alcohol_df.sort_values("region", ascending=False) print(sorted_drinks) Sort my multiple variables by passing a list to the method sorted_drinks = alcohol_df.sort_values(["region", "year"], ascending=[True, False]) print(sorted_drinks) Subset columns to only see the data in a particular column print(alcohol_df["region"]) To subset multiple columns to only see the data in the particular columns print(alcohol_df[["region", "year"]]) 2.

I didn’t expect learning to code to feel like therapy. I remember the first time I started learning how to code. I was 17 years old, wide-eyed and full of curiosity. I remember watching Corey Schafer’s Python playlist over and over again like it was a sacred text. Here’s the link if you wanna check it out. Doesn’t it say a lot about life, that I went from a 17-year-old kid who had never even touched code, to a full-on software engineering undergraduate, cybersecurity engineer, and freelancer in both fields? But it doesn’t end here. Not even close. In fact, I feel like I’m just getting started. Because the tech world never stands still, and neither will I. Because this path I’m on? It’s not a sprint. It’s not a straight line. It’s a lifelong climb, and the summit keeps moving. So no, this isn’t the end. Join me on this path. 📬 Subscribe for more at: azizontech  ( 5 min )

A constructor function is a special type of function used to create and initialize objects in programming, particularly in object-oriented languages like JavaScript. Think of it as a blueprint or factory for making many similar objects. Imagine you're managing a car manufacturing company. Every car you build shares the same structure—engine, wheels, color, and brand—but each one has its own values. Instead of manually building each car from scratch, you use a car-making machine (constructor function). You input values like color, brand, and engine size, and the machine builds the car for you. function Car(brand, color, engineSize) { this.brand = brand; this.color = color; this.engineSize = engineSize; } This is the constructor function. To create a car: let car1 = new Car("Toyota", …  ( 4 min )

In today's rapidly changing programming world, Rust and Zig are the hottest topics. Both modern, low-level programming languages exist mainly to address shortcomings in older systems programming languages like C and C++. But which one would you choose to learn in 2025? Is Zig a competitor to Rust, or does it remain the reigning champion? We will discuss their pros and cons and their best use cases. The Rise of a New Competitor But now, there comes a new competitor: Zig. Lightweight and flexible, it's not going unrecognized by the low-level developers with its focus on manual memory management, compile-time safety, and minimal run-time overhead. With this adoption trend, that question arises among many of how true this is: ''Is Zig a real competitor to Rust?'' Hence, in the following article, we shall compare Rust and Zig, note significant differences, and possibly help you decide on which of the two you are planning to learn in 2025. Why is Rust So Popular? 1. Memory Safety Without a Garbage Collector 2. Fearless Concurrency 3. Performance on a Par With C and C++ Rust provides zero-cost abstractions that allow a high level of expressiveness in writing programs while incurring little or no run-time overhead. In many cases, Rust is as fast as or faster than C/C++. 4. A Thriving Ecosystem and Strong Tooling Rust Uses and Applications For massively scalable applications, Rust fits the bill. The flip side of such scalability would certainly be a lot of complexity, and this is where Zig fills the void. The Minimalist Challenger: Zig Unlike Rust's expensive and stringent powers with sections for systems programming, Zig is strictly minimalist and performance-optimized with no specific automated memory management.

Now this... this is where the real battle began. On one side, Blockchain Development — a world of code, decentralization, and smart contracts. Forex Trading — candles, charts, patterns, and pips. So where do I go from here? At first, it was chaos. I’d be deep in writing a smart contract in Solidity, then moments later, I’d find myself back on TradingView, analyzing XAU/USD like my life depended on it. My mind was constantly bouncing between gas fees and candlesticks. I knew something had to give — this back-and-forth was draining my focus, and if I kept going like that, I’d end up mastering neither. So I paused. “How do I fix this?” After some much-needed clarity, I narrowed it down to three options: Quit trading and go all-in on tech. Quit tech and go all-in on trading.

I’m building a project using Next.js (latest version) with Tailwind CSS and deploying it to Vercel. The issue is: all design changes (layout structure, visual style updates, etc.) show up perfectly in local development, but they don’t appear at all on the production URL after deployment. Things I’ve tried: git push to main runs without errors. Vercel deployment shows status as “Ready” with no build errors. Forced browser refresh (Ctrl+Shift+R), cleared cache, used incognito mode. Tested on multiple browsers and devices. What could prevent design changes from being reflected in production? I’d appreciate any advice or suggestions. I’ve repeated the steps multiple times and still can’t get the updated design to show live.  ( 3 min )

In the digital age where apps talk to servers, systems talk to each other, and devices sync data across continents, JSON stands tall as the standard language of communication. Simple in form but powerful in function, JSON is a foundational technology in software development, used across web, mobile, IoT, AI, databases, and cloud platforms. Let’s break down JSON from theory to real-world practice, with examples and project-level applications. JSON (JavaScript Object Notation) is a lightweight text-based format for representing structured data. Despite its name, JSON is language-agnostic, and supported natively or via libraries in virtually all programming languages.

Cloud computing isn't simply a catchphrase in today's digitally first society; it's the foundation of contemporary company operations. The cloud makes speed, size, and cost-effectiveness possible for everyone from start-ups releasing mobile apps to multinational corporations overseeing operations worldwide. However, "the cloud" isn't a universally applicable answer. Different kinds of cloud services are available, depending on what you're building and how much control you desire. Let's dissect them. 1. Infrastructure as a Service (IaaS) What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers and system administrators who want flexibility without managing hardware. 2. Platform as a Service (PaaS): What User Manages: What the Provider Manages: Use Cases: Examples: Ideal for: Developers who want to build applications quickly without worrying about backend setup. 3. Software as a Service(SaaS): What User manages: What the Provider Manages: Use Cases: Examples: Ideal for: End-users or businesses who want to use powerful software without installing or maintaining it. What Should You Pick? Choose Infrastructure as a Service (IaaS) if you require total control over your environment. Select PaaS if you wish to concentrate just on development. SaaS is your friend if all you need to do is use an app to get started quickly.  ( 4 min )

Understanding the Issue of Missing URL Parameter in FastAPI When using a Next.js frontend to send data to a FastAPI backend, it's important to ensure that all parameters, including files and URLs, are properly formatted and sent in the FormData. In your case, while the username and files are being received correctly by the FastAPI endpoint, the urls parameter is showing up as None, which can be quite perplexing. Let’s dive into the potential reasons why this is happening and how to resolve it. Reasons Why the URLs Parameter Might be None Incorrect FormData Structure: One common reason for receiving None in the FastAPI backend for the urls parameter could be due to the way the data is appended to the FormData in the Next.js code.

Legal tech is booming, but building for the legal industry comes with hidden technical, ethical, and compliance challenges..here’s what every dev should understand before jumping in. So you want to build the next AI tool that revolutionizes law? Great!!legal professionals need better, faster tools. But before you start coding your first legal document parser or compliance bot, there are real-world landmines to avoid. Legal data is often highly sensitive and subject to strict confidentiality rules (think attorney–client privilege or court-sealed documents). Scraping, storing, or even training on this kind of data without safeguards could expose you and your users to legal risk. Also, when your AI outputs a compliance decision (e.g., GDPR audit findings or AML flags), you're not just providing a "suggestion", you may be influencing legal liability. Many jurisdictions require explainability, auditability, and even human-in-the-loop systems. Legal language is dense, full of nuance, and jurisdiction-dependent. Two identical phrases may have opposite meanings depending on where and how they appear. Of course, you know there are already APIs and frameworks built for legal applications. Don’t reinvent the wheel. Legal professionals are risk-averse by design. They value clarity, documentation, and accuracy over speed. Your app’s UX must reflect that. If they can’t trust it, they won’t use it, no matter how smart it is. Are you building legal tech tools? What challenges have you run into? Drop a comment or connect—let’s push the future of legal AI forward, together.  ( 3 min )

昨天的文章介绍了使用uniapp跨平台鸿蒙应用时如何配置开发环境和运行调试项目,今天介绍一下uniapp项目目录的结构。 上面的两个文件夹pages中存放的是项目的页面，static则是存放静态资源的文件。 继续往下面看，App.vue文件打开可以看到它里面存放了项目的生命周期函数，比如项目启动、项目退出等等。 index.html相当于项目的根页面，它虽然也属于页面，但是在uniapp中通常是不需要大家修改的，因为可以看到里面有一个id是app的容器，我们在项目中写的所有代码最终都会注入到这个容器中。 Main.js是整个项目的核心入口文件，负责初始化Vue实例和全局配置 Manifest.json中存放了项目的各种配置文件，项目的名称、版本、描述、各个平台的的运行配置都在这里。 Pages.json中存放了项目中所有的页面路径和全局样式，尝试在globalStyle中的样式做一些修改，项目的全局样式就会被改变。而当新建了一个页面时，也会在这里自动注册。 最后的uni.scss文件，打开可以看到它已经给出了解释，这里是uni-app内置的常用样式变量。 以上就是uniapp项目初始化后的项目结构，还没结束，当我们运行项目后，还会新增unpackage目录，打开可以看一下是不是很熟悉，编译器把uniapp项目编译成了鸿蒙项目，这就是跨平台开发的运行原理。 以上就是对uniapp项目结构的详细解读。经历了两天的项目环境搭建和介绍，接下来的教程我们会进入到正式的跨平台开发编码环节，欢迎您持续关注。  ( 2 min )

I've embarked on a project that, although simple, has been a challenge. I've built my personal website, resume, and code visible on GitHub. This has been a bit of a challenge, because I knew my code would be visible and analyzed by recruiters. Still, I did it with love and enjoyed the experience. With it, I've had to be a software architect, content creator, project manager, developer, and SEO. Along the way, I've learned and grown. I've seen things I want to take to other projects, and the importance of following the principles of clean code, design patterns, and an architecture that's easy to scale. This project is built with Angular version 19. I use standalone components, computed properties, and effects, as well as rxResource and new features of the framework. For the UI, I used Angular Material, but minimally. The design is simple, designed so that people with visual impairments can use it without problems, balancing color contrast and good visual results. The result is my personal website, which I've been building little by little, and which I'm now sharing with you at www.antonioubedamontero.com. I'm making small improvements, adding features, and polishing what will become my brand image.

One of Zig’s most powerful features is its ability to run code at compile time. This enables code generation, validation, and optimizations that would be much harder (or impossible) in many other languages. In this tutorial, we’ll walk through practical examples of Zig's compile-time programming and how you can use it effectively. You can run code at compile time using comptime: const std = @import("std"); const num = comptime calculate(); fn calculate() usize { std.debug.print("Evaluating at compile time\n", .{}); return 42; } Here, calculate() is run at compile time, and num becomes a constant value. comptime Parameters Zig lets you write generic functions and types using comptime parameters: fn identity(comptime T: type, value: T) T { return value; } const result = ide…  ( 4 min )

Zig’s build system might look unfamiliar at first, but it's actually one of its greatest strengths. By using Zig itself as the configuration language, build.zig gives you full programmatic control over compiling, linking, testing, and more — without external tools or DSLs. build.zig? Every Zig project with multiple files or custom build steps uses a build.zig script. This script defines how to build your application using Zig's std.Build API. build.zig Example Here’s a simple build script for a Zig executable: const std = @import("std"); pub fn build(b: *std.Build) void { const target = b.standardTargetOptions(.{}); const mode = b.standardReleaseOptions(); const exe = b.addExecutable(.{ .name = "hello", .root_source_file = .{ .path = "src/main.zig" }, …  ( 4 min )

Introduction If you're new to Dart and want to manage data efficiently, using a class to store instances in a map is a great approach. In your case, you're trying to maintain a persistent map that holds instances of myCar, but you're encountering an issue where the map is reset every time addInfoToMap() is called. Let's explore why this is happening and how to fix it. Why is myMapOfCars Being Reinitialized? The main reason myMapOfCars is reinitialized each time is that it's defined as an instance variable (implicitly associated with each instance of the myCar class) rather than as a static variable that belongs to the class itself. Each time you create a new instance of myCar, a new myMapOfCars is created, which is why it appears empty when you call addInfoToMap(). Solution to Persist Data…  ( 4 min )

Enums and error sets in Zig offer powerful ways to model states and failures with clarity and precision. In this tutorial, we’ll cover the basics, then walk through real-world uses of both types — and how they play nicely together. Enums let you define a type with named values: const Direction = enum { North, South, East, West, }; You use them like this: const dir = Direction.North; Zig will guarantee at compile time that dir is one of the defined directions. Zig encourages exhaustive switching — the compiler checks for missing cases: switch (dir) { Direction.North => std.debug.print("Going up\n", .{}), Direction.South => std.debug.print("Going down\n", .{}), Direction.East => std.debug.print("Going right\n", .{}), Direction.West => std.debug.p…  ( 4 min )

Introduction When working with Flutter, developers often face challenges while integrating external resources, such as images from different domains. A common issue arises when trying to load YouTube video thumbnails, leading to errors that may hinder the application's functionality. If you are using the youtube_plyr_iframe package in your Flutter project and encountering problems fetching YouTube thumbnails using Image.network, you are not alone! Understanding the Problem The error you are experiencing typically stems from restrictions placed on cross-origin resource sharing (CORS). YouTube images, such as the thumbnail https://i3.ytimg.com/vi/TyimCGEkiUc/maxresdefault.jpg, may encounter loading issues if they don't permit cross-origin requests. While loading other images works seamlessly…  ( 5 min )

Do you know the difference between Future and Stream in Dart? Both handle asynchronous operations, but have different purposes: Future: returns a single value in the future.

In the world of web applications, handling redirects efficiently can often lead to complex scenarios, especially when query parameters are involved. A common challenge arises when a proxied server, such as Keycloak, issues a redirect response that strips these important parameters. This article explores how to effectively capture and forward query parameters using Nginx and Lua, offering a practical solution to your business requirement. Understanding the Problem Redirects can be tricky, particularly with status codes like 302 that don’t maintain the query parameters sent to the original request. In your case, after the following steps: Client requests an authorization code from Keycloak. Keycloak returns a 302 redirect, losing essential query parameters. You’re left without critical data …  ( 5 min )

This is a submission for the Amazon Q Developer "Quack The Code" Challenge: Exploring the Possibilities At my company, we still don’t have a proper tool to manage secrets. So, naturally, people come up with their own solutions—some of them not very secure. I had the idea of using AWS Secrets Manager as a secure place to store our secrets. But there was a challenge: Then I discovered that a single AWS Secret can store up to 64KB, which is more than enough for a bunch of simple strings. That got me thinking... So I did it! :) Introducing aws-vault-lite — a lightweight secret manager I built in just one night (with a hand from Amazon Q). What is? That was a pretty polite intro, wasn’t it?

In the modern data-driven world, working with relational databases is inevitable for backend engineers, full-stack developers, and data analysts. And at the heart of relational data querying lies one foundational skill: SQL JOINs.

I loved text adventures as a kid. Still do. I even wrote a few, though I never had the courage to show them to others. The DnD games I played with friends had a step-up on this, of course: a human being who could intelligently respond to anything you tried. It was only a matter of time before somebody had the idea to use AI for adventure games, and there are some interesting options out there I'm keen to try sometime: AI Dungeon, DREAMIO and Friends & Fables.

The government of El Salvador continues stacking Bitcoin (BTC) for its national crypto reserve, despite an ongoing deal with the International Monetary Fund (IMF) stipulating that the Central American country stop using public funds to purchase Bitcoin as one of the conditions for a loan agreement. According to data from the El Salvador Bitcoin Office, the country acquired an additional seven BTC in the last seven days, bringing its total holdings to 6,173 BTC, valued at over $637 million. El Salvador's Bitcoin Office has continued its steady pace of Bitcoin acquisitions months after the IMF agreement was signed and shows no sign of halting its Bitcoin purchases. The Central American country is one of the only nations actively purchasing Bitcoin in open market operations, and its national …

Investors of Bitcoin Satoshi's Vision (BSV) — a hard fork of Bitcoin Cash (BCH), which itself is a hard fork of the Bitcoin (BTC) protocol, are attempting to revive a 2019 lawsuit against crypto exchange Binance for delisting the altcoin, which the litigants claim stunted the price of BSV.   According to Law360, attorneys for the plaintiffs argued that a July 2024 decision from the UK Competition Appeal Tribunal dismissing the "loss of chance" claim made against Binance for delisting the token, should be reconsidered. The litigants demanded $9 billion in damages, in the original case. The investors continue to claim that Binance's 2019 delisting of BSV and similar major exchange delistings are the primary drivers of BSV's long-term price decline and its failure to attract the investor atte…

Strategy, a Bitcoin (BTC) treasury company, is accumulating Bitcoin at a faster rate than total miner output, giving the supply-capped asset a -2.33% annual deflation rate, according to CryptoQuant CEO and market analyst Ki Young Ju. "Their 555,000 BTC is illiquid with no plans to sell," the analyst wrote in a May 10 X post. "Strategy's holdings alone mean a -2.23% annual deflation rate — likely higher with other stable institutional holders," Ju continued. Michael Saylor, the co-founder of Strategy, is an outspoken Bitcoin advocate who evangelizes the scarce digital currency to potential investors and has inspired many other companies to adopt a Bitcoin treasury plan.

Opinion by: Kevin Rusher, founder of RAAC It’s a volatile world out there. This year, we’ve seen stocks take a wild ride as gold has pumped and crypto has been caught somewhere in the middle. Investors have dumped risk assets and scrambled for safe havens. Gold is leading the charge. While gold is safe, it is not very hard-working. Unlike cash and treasuries, the yellow metal does not generate income. Now, more than ever, investors need to be able to earn yield on gold — particularly in the decentralized finance (DeFi) sector. The only way to make money from gold is to buy low and sell high. Most investors don’t tend to buy gold like this. That’s for good reason — over the long term, gold’s performance is typically consistent, if not without a few peaks and troughs here and there, as we h…

Key takeaways: Ether is set for its best weekly gain since May 2021. Ethereum’s Pectra upgrade, mega-whale accumulation, and a major short squeeze fuel the rally. Technical patterns suggest a potential 40% rally toward $3,400 as ETH bounces off key support. Ether (ETH) is on course to record its best weekly performance since May 2021, having risen by over 37.50% in the week ending May 11, including 10.30% gains in the last 24 hours. US tariff updates, Pectra upgrade boost Ethereum The announcement of a new trade agreement between the US and the UK on May 8 and the initiation of US-China trade talks afterward have bolstered upside sentiment in Ether and the broader crypto market. Additionally, Ether benefits from its Pectra upgrade on May 7, which introduced key improvements like higher…

After 4chan was hacked on April 14 and vast troves of user and moderator data were leaked online, the controversial website quickly went down, and many believed it would never recover. However, less than two weeks later, the imageboard was back online, defiant as ever. “4chan is back,” an official blog post proclaimed. “No other website can replace it, or this community. No matter how hard it is, we are not giving up.” The imageboard has left its mark on the world in many consequential ways, birthing countless memes and conspiracy theories, serving as a platform for political movements ranging from the alt-right to Anonymous, and acting as a dumping ground for leaks and hacks of all sorts.  Crypto is no exception, with 4chan also a historically influential gathering place to share altcoin …

On April 29, UK Finance Minister Rachel Reeves unveiled plans for a “comprehensive regulatory regime” aimed at making the country a global leader in digital assets. Under the proposed rules, crypto exchanges, dealers, and agents will be regulated similarly to traditional financial firms, with requirements for transparency, consumer protection, and operational resilience, the UK Treasury said in a statement released following Reeves’ remarks. Per the statement, the Financial Services and Markets Act 2000 (Cryptoassets) Order 2025 introduces six new regulated activities, including crypto trading, custody, and staking. Rather than opting for a light-touch regime similar to the EU’s Markets in Crypto-Assets (MiCA), the UK is applying the full weight of securities regulation to crypto, accordin…

Hong Kong-based fintech firm RedotPay has reportedly launched its cryptocurrency-enabled payment cards in South Korea, positioning itself as a potential disruptor in a market dominated by traditional credit card firms and mobile payment services. The company’s crypto debit cards—both physical and virtual—are now accepted at all Korean merchants that support Visa, according to a May 9 report by The Korea Economic Daily. The move marks RedotPay’s latest step in global expansion, following its earlier partnership with Visa and BIN sponsor StraitsX in February 2025 to enhance cross-border crypto payment capabilities. RedotPay, founded in 2023, has rapidly scaled since the soft launch of its crypto card program in late 2024. It now serves more than 4 million users worldwide. In South Korea, use…

Robert Kiyosaki, businessman and best-selling author of Rich Dad Poor Dad, is once again sounding the alarm on the dangers of centralized monetary policy — urging his followers to abandon what he calls “fake money” and adopt alternatives like Bitcoin, gold, and silver. In a May 10 post on X, Kiyosaki backed a hardline stance against central banking systems, particularly the Federal Reserve, while quoting former US Congressman Ron Paul. Ron Paul, a longtime critic of the Fed and author of End the Fed, described interest rate setting by central banks as “price fixing,” equating it to socialist and Marxist economic control. Paul warned that such mechanisms erode personal wealth and undermine economic freedom — a sentiment that aligns closely with Kiyosaki’s long-held concerns. “Fake money lea…

BlackRock’s spot Bitcoin ETF (IBIT) capped off the trading week with another day of inflows, pulling in $356.2 million on May 9. The fund has now extended its inflow streak to 19 consecutive days — its longest run of inflows so far this year. IBIT’s inflow streak has been ongoing since April 14, and has coincided with a volatile Bitcoin (BTC) market, with the asset trading between $83,152 and $103,000 over the period. However, market sentiment has been increasing after the asset reclaimed and held above the $90,000 price on April 23 before reclaiming the $100,000 price on May 8 for the first time since Feb. 1. Bitcoin ETFs ticking along as Bitcoin price spikes Over the past trading week alone, IBIT posted $1.03 billion in inflows, according to Farside data. Prior to the current 19-day stre…

Sovereign Wealth Funds are already gaining exposure to Bitcoin, but significant allocations won’t happen until the United States establishes clearer regulations for the digital assets industry, says SkyBridge founder Anthony Scaramucci. “I think they are buying it, I think they are buying it on the margin,” Scaramucci, former White House director of communications during US President Donald Trump’s first term, said on Anthony Pompliano’s podcast on May 8. Legislation will lead to “large blocks of buying” “I don’t think it is going to be a gigantic groundswell of buying until we greenlight legislation in the United States,” he added. Scaramucci previously said in a February interview with the Financial Times that he expects the US government to propose crypto legislation in November. SWFs a…

Strategy founder Michael Saylor says Bitcoin hasn’t reached $150,000 yet because holders without a long-term outlook have been selling off while a new cohort of investors are beginning to enter the market. “I think we’re going through a rotation right now,” Saylor said on the Coin Stories podcast with Natalie Brunell on May 9. The lack of “10-year investor mindset” led to Bitcoin sell-off Saylor said “lots of non-economically interested parties are rotating out of the asset.” However, at the same time, “a new cohort of investors are entering.” “A lot of Bitcoin, for whatever reason, was left in the hands of the governments and the hands of lawyers, and in the hands of bankruptcy trustees,” he added. Strategy’s Michael Saylor spoke to Natalie Brunell on the Coin Stories podcast. Source: Na…

Key takeaways: ETH price rallied by 22% on May 8, but demand for spot ETH ETFs and derivatives remains muted.  President Trump’s reversal on certain altcoins aligns with ETH’s renewed outlook.  Ether (ETH) posted an impressive 29% gain between May 8 and May 9, likely marking the end of a 10-week bear market that bottomed out at $1,385 on April 9. This sharp move triggered the liquidation of over $400 million in short (sell) ETH futures positions, suggesting that whales and market makers were caught off guard. Despite the surge, traders have maintained a neutral stance in ETH derivatives. Whether this apparent lack of conviction reflects a genuine trend reversal or merely precedes another test of the $2,000 level remains to be seen. Ether 3-month futures annualized premium.

You want to pass variable args to a function, like so: const doSomething = (a: string, b?: string, c?: string): void => {}; However, TS didn't like it... // não bom const args = [['a', 'b', 'c'], ['a', 'b'], ['a']]; args.forEach((arg) => { // A spread argument must either // have a tuple type or be passed // to a rest parameter. ts(2556) vvvvvv doSomething(...arg); }) The problem is that doSomething expects one to three arguments of type string, but arg is typed as string[]. We need to narrow the type down, to match the arguments of doSomething() // bom const properTypedArgs: [a: string, b?: string, c?: string][] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) This works, but if you don't fancy re-typing the function's argument type defs or don't have it handy, TS utility type got you covered: // ainda melhor const properTypedArgs: Parameters[] = [['a', 'b', 'c'], ['a', 'b'], ['a']]; properTypedArgs.forEach((arg) => { doSomething(...arg); }) That's all!

Today's question Create a React application that allows users to create, display and delete blog posts. Solution The first step is to evaluate the boilerplate provided. There are 3 boilerplate files: Home.js import React from "react"; import Input from "./Input"; import PostDisplay from "./PostDisplay"; function Home() { return ( {"Title"} {"Description"} Delete ); } export default PostDisplay; The Home component(file) is provided as the parent component, which manages the state of the application. So, variable states for all blog posts, and a single new blog post will be created. The input component is responsible for creating new blog posts, therefore, the variable states for new blogs will be passed into it after it has been created in the Home component. Then, the PostDisplay component, which handles showing all blog posts, will have the state for all blog posts passed into it.  ( 3 min )

Wanted to share a very quick on something I learned that was pretty useful to me, so thought it might be useful to others. Here is a scenario that some of you might be familiar with: You have a successful Amazon Q Developer session, and then maybe a few days later, you are trying to recall exactly what you did and how you put your prompts together - what can you do? As it turns out, a recent update to Amazon Q Developer was a big help. In the Amazon Q Developer chat interface, there is a new icon next to the different tabs (its an icon of a click, which when you hover over says "View Chat History") which when you click on this, it will bring back a list of previous chats that have been recorded. What does this mean? In the "~/.aws/amazonq/" directory there is a "history" directory, and looking at it, it contains a number of time/date stamped json files. ├── history │   ├── chat-history-0f97086b54fd7d6128dfd80426dfd63d.json │   ├── chat-history-10d817f64fc99f04badf1568a6c23814.json │   ├── chat-history-deba93a681a17ae26ff2b977acf0ba97.json │   ├── chat-history-fa5091a7425e7938fe770a584b63076e.json │   └── chat-history-no-workspace.json These are what the Amazon Q Developer VSCode plugin now produces as you start using it. That said, because I had deleted my project, and so I was unable to get this from VSCode itself. Aarrgh, I thought to myself. Not to worry though. I still had the files in the history directory. So reviewing these with my favourite json viewer (I knew which file to use, aligning date stamps from these and the code files in my project workspace), allowed me to extract all the history, including prompts and responses. Very handy to know if you want to go back in time. This saved me, so hoping it will help others who are looking to recover what they did.  ( 3 min )

When I started writing code, I thought the goal was perfection. A flawless feature. A zero-bug release. The cleanest, DRYest, most elegant solution to every problem. But if there’s one thing software engineering teaches you—again and again—it’s this: Perfect doesn’t ship. Progress does. Behind every product you love, every app you use daily, and every "it-just-works" moment, there’s a messy history of trade-offs, iterations, rewrites, and late-night breakthroughs. There’s never been a perfect version—only the best version for right now. “If you’re aiming for perfection, you’ll never release,” he says. “But if you aim for learning, you’ll improve with every commit.” That’s the shift that happens when you grow—not just as a coder, but as an engineer. Early Career: Learning the Rules Most engineers begin their journey by learning the rules. Mid-Career: Building Beyond Code As you gain experience, your job evolves. You're not just writing functions—you’re: The Myth of Mastery There’s a moment many engineers hit mid-career: you expect to feel confident, but instead, you feel behind. Late Career: Scaling Impact By the time you’re a senior or staff engineer, the problems you solve are rarely just technical. Letting Go to Grow So what does it really mean to grow as a software engineer? Final Thoughts: We’re All Still Learning No matter where you are in your career—just starting out, mid-level and unsure, or senior and scaling—remember this: You don’t have to be perfect. You just have to keep learning. Great software is built by people who care enough to try, fail, ask, share, and try again. People like Abhishek Desikan, who show that engineering is not just about building products—it’s about building people, teams, and ethical systems that serve others well. “We’re not just writing code,” Desikan reminds us. “We’re writing the story of how people experience technology.” And when we do that with care—even if it’s not perfect—we’re already doing something right.  ( 5 min )

Introduction When developing high-performance applications, managing concurrency efficiently is crucial. In this article, we will address how to ensure that multiple tasks run in parallel on iOS 15 while using Swift's async/await and TaskGroup. Specifically, we will look into a puzzle-generating application that encounters parallel execution issues on iOS 15. We will explore the reasons behind the problem and provide actionable solutions to ensure optimal performance. Understanding the Issue The code example provided describes a puzzle generator that works based on a Latin square. Running four different tasks concurrently should ideally distribute the CPU load effectively across available cores. However, when tested on iOS 15, it appears that only one task is being executed at a time. This…  ( 5 min )

I read a lot, and always have a couple of books on the go at any one time (currently Linchpin by Seth Godin and The Prisoner of Heaven by Carlos Ruiz Zafon. I am always on the lookout for a new book though, and this thread on LinkedIn sparked an idea (check the comments) about building a simple book sharing application that a group of friends might use to share good books they recommend. I had an idea of what I wanted to create: a simple web application that a group of friends could use to create lists of the books they are reading, provide ratings and comments, and then allow them to share and borrow books they might be interested in. I had a couple of hours whilst I was travelling, and wanted to use Amazon Q CLI to build this. Why? I have been slowly switching from VSCode to Zed, and the…  ( 10 min )

The art of runway walking represents far more than simply moving from point A to point B—it’s a carefully honed skill that conveys brand aesthetic, garment movement, and professional polish. While television and social media often portray modeling as effortless, the reality involves precise technique, body awareness, and adaptability to different show requirements. The walk serves as a model’s primary tool for bringing clothing to life, requiring equal parts discipline and artistry to execute effectively. Proper runway technique begins with posture that appears relaxed yet controlled. The ideal stance starts with shoulders pulled back and down, creating an open chest without appearing stiff. The spine maintains natural alignment from the tailbone through the neck, allowing for fluid moveme…  ( 5 min )

Introduction When working on a full-stack application using ASP.NET and Blazor, you might face challenges while managing relationships between entities in your databases. One common issue developers encounter is the inability to assign a Client to a Job due to errors like "Cannot assign an existing ID."

Hello everyone! Ever wrestled with finding the smallest contiguous subarray within an array that sums up to a given target? It's a classic problem, and today we'll explore two contrasting approaches in JavaScript: the elegant sliding window and the straightforward brute force. Let's dive in! Given an array of positive integers nums and a target integer target, our mission is to find the smallest contiguous subarray whose elements sum up to be greater than or equal to the target. If no such subarray exists, we return 0 (or some other indicator). The most intuitive approach is to consider all possible subarrays. We can achieve this using nested loops: The outer loop iterates through all possible starting indices i from 0 to n-1 (where n is the length of the array). The inner loop iterates …  ( 4 min )

Like a lot of devs, I built a side project that scratched a personal itch: an invoice generator. But instead of going full SaaS startup mode, I treated it as a challenge—build something clean, useful, and fast, with a real login system, server-side PDF generation, and as little overhead as possible. The result is InvoiceDen, a React-based web app hosted on Cloudflare Pages, with backend functionality on an EC2 instance, all for about $8/month. Here’s what I learned architecting it on a shoestring budget — and how you can do something similar without spinning up Kubernetes or draining your wallet. The app is split into a classic frontend + backend setup, but optimized for cost and simplicity. Frontend: React app hosted on Cloudflare Pages Static deploys, global CDN, zero dollars Backend: Sm…  ( 5 min )

It’s a common story: a team launches their application to the cloud, celebrates the deployment and then, weeks later, is shocked by a ballooning cloud bill. What started as a low-cost, high-efficiency architecture suddenly feels bloated and unpredictable. The truth is, most cloud cost spikes don’t come from initial deployments, they come from what happens after. And if you don’t have visibility or automation in place, it’s easy to lose control. Here’s what’s really driving those post-deployment cloud cost spikes and what you can do to stop them with the help of Kuberns. Idle resources that never got turned off After deployment, environments like staging, dev, or feature branches are often left running. Temporary services that were only meant for testing remain active, silently consuming…  ( 4 min )

I recently tried out 5 CMS platforms to use for our blog on sliplane.io and wrote a short section about why I did not like WordPress. Mainly that it’s bloated and plugin-heavy. Some people immediately started firing at me, telling me SEO would be "whack" if I used anything else... as if SEO was a feature toggle in WordPress. But let’s be clear about something: Google doesn’t rank your site based on your CMS! Google doesn’t care if you’re using WordPress, Webflow, Drupal or your content is served from a Google Sheet. Google doesn’t have a CMS bias built in. It doesn’t know how "clean" your CMS feels or cares about how many Yoast plugins you’ve installed. It only sees data. Numbers. Metrics. That's it. Here’s what Google can measure: Page speed – how fast your site loads. Mobile usability …  ( 4 min )

Use case - what it solves So If you're familiar with docker containers so far (if not, read my previous two articles on this), When there's more than 1 container, and they have to interact, there's some things you have to repeat, like: pulling image & creating a container. allocate volumes, pass ENV args, etc to container have all containers running in same network . Now if there's 3,4,5,.. or more, it gets more hectic, see where this is going? Docker compose solves that, by "composing" up your containers config in a file type called "yaml" (its similar to json - a data format, usually for configs). You still have things like Dockerfile and concepts of containers are the same, its just the process that's simpler. A quick example of 3 containers rolling up using docker compose.

If you're learning JavaScript, you've likely come across closures — a concept that's easy to overlook but incredibly powerful. In this post, I'll break down closures using a real-world coding example: computing Fibonacci numbers with memoization. A closure is when a function remembers the variables from its lexical scope, even after the outer function has finished executing. In other words, inner functions can "close over" variables defined in an outer function — keeping them alive between calls. Let’s start with a simple (but inefficient) recursive Fibonacci implementation: function fib(n) { if (n <= 1) return n; return fib(n - 1) + fib(n - 2); } console.log(fib(10)); // 55 This works, but it's horribly inefficient for large n due to repeated calculations. Let’s use a closure to store previously computed Fibonacci numbers (aka memoization) and avoid redundant work. function createFibonacci() { const memo = {}; function fib(n) { if (n in memo) { return memo[n]; // Return cached result } if (n <= 1) { memo[n] = n; } else { memo[n] = fib(n - 1) + fib(n - 2); } return memo[n]; } return fib; } const fibonacci = createFibonacci(); console.log(fibonacci(10)); // 55 console.log(fibonacci(50)); // 12586269025 — much faster due to caching! memo is defined once inside createFibonacci() and persists across calls to fib() because of closure. Even after createFibonacci() has returned, the fib() function still remembers the memo object. This is the closure in action: the inner function keeps access to its outer scope. Closures allow us to: Preserve state across function calls without polluting the global scope. Create factory functions like createFibonacci() that generate self-contained logic. Enable powerful patterns like memoization, function factories, and data encapsulation. Closures aren't just theoretical — they’re a practical tool for writing clean, efficient JavaScript.

In Go version 1.24, the encoding/json package introduced the omitzero tag, making the behavior of ignoring zero-value fields more explicit and customizable. This article provides a detailed explanation of how to use the omitzero tag. omitzero Tag The omitzero tag is used to control which zero-value fields should be omitted when serializing Go objects into JSON. Unlike the omitempty tag, which omits empty-value fields, zero values and empty values, while similar, are not equivalent in Go. For example: For the time.Time type, the zero value is "0001-01-01T00:00:00Z", which is not considered an empty value. For a slice field like IntSlice []int, both [] and nil are considered empty values. omitzero Precise control: Explicitly omits zero-value fields, rather than empty-value fields. Cust…  ( 4 min )

AKA: The one where I didn’t break anything on purpose. This week was less about tinkering with new AWS services and more about turning the spotlight on the community side of cloud development. If you’ve been following along, you know I’ve spent the last few weeks deep in LocalStack. Testing services, simulating chaos, debugging stateful nightmares (good times!). But this week, I shifted gears. Instead of code, I focused on content and connection. The LocalStack community is incredibly helpful. People show up daily with questions, bug reports, and clever workarounds. It’s a support-driven space that works. But I’ve been noodling on a bigger goal: How do we turn a support community into a space for shared learning, storytelling, and collaboration? I don’t have the full answer yet, but I’ve s…  ( 4 min )

The eye-roll isn’t a personality trait. It’s a warning sign. It starts as a harmless reflex. Someone drops a half-baked feature in sprint review, proudly demoing what amounts to a glorified loading spinner - and your brain whispers, “Seriously?” Another project dies on the vine, killed by the same meetings that birthed it, and you think, “Of course it did.” You’ve seen this show before. You know how it ends. Congratulations. You’ve unlocked senior cynicism. It feels like insight. Like armor. But it’s actually rust. And if you don’t watch it, it will eat straight through your usefulness. Cynicism is ego’s favorite disguise. It lets you feel smart without risking anything. If something fails, you “saw it coming.” If it works, you’re still right - just surprised. It’s the ultimate no-lose b…  ( 5 min )

Understanding Reflection in Go with Nested Structs Reflection is a powerful feature in Go that allows you to inspect and manipulate objects at runtime. In this blog post, we'll explore how to use reflection with nested structs and interfaces, specifically focusing on printing the contents of structs that implement a certain interface. We will fix the example provided, ensuring that our code dynamically recognizes interface implementations without explicitly mentioning the structs. The Problem with Your Reflection Code In your provided code, you are encountering an 'ErrUnhandledType' error when trying to directly recognize the PrintStr interface during iteration. This occurs because the Field(i).Interface() method retrieves the value of the struct, not the pointer that implements the PrintS…  ( 5 min )

I’m not the most careful person when it comes to laptops — or any device, really. At one of my former jobs, I ended up replacing my machine three times (not proud of it 💀). By the third round, I was already sick of going through the whole setup process again. That pain led me to discover something that changed my workflow for good: dotfiles. In this article, I’ll walk you through what dotfiles are, why they matter, how to version-control them, and how to back up and restore your full dev setup without the pain. Dotfiles are hidden configuration files on Unix-based systems (like macOS, Linux, or WSL). They store preferences for tools like your shell, text editor, terminal multiplexer, and more — allowing you to personalize your development environment. By version-controlling your dotfiles …  ( 6 min )

Welcome to another installment in Learning How to Learn. For context, I am on a journey to teach myself backend. To do that, in addition to all of the technical knowledge, I also need to know how to learn and be a teacher. So today we will breach fundamental concepts in both areas: levels of understanding and servers. Lets start with levels of understanding. In the world of education, there is a helpful framework called "Bloom's Taxonomy" that breaks them down easily: Remembering Understanding Applying Analyzing Evaluating Creating This covers everyone from the newest student to the oldest expert. So if I have this goal to learn backend, my very next question is to what level should I be learning backend? Well my goal is ultimately to be employable, and the standard for employment…  ( 6 min )

Hello World So you want to make pictures with code? Perfect—p5.js is basically Processing’s JavaScript‑savvy little sibling, built for the browser and ridiculously easy to spin up. Drop one script tag, write a setup() and a draw(), and you’re already painting pixels. The library handles all the boring canvas plumbing, so you can jump straight to the fun bits -- random lines, kaleidoscopic color, even interactive sketches -- without wrestling a build system or a GPU API. In this post we’ll start from absolute zero: an index.html that pulls in the p5.js CDN, a bare‑bones script.js with createCanvas(), and a first “hello world” doodle driven by a sprinkle of randomness. If you’d rather poke around before we dive in, crack open the official docs at p5js.org or play in the Web Editor -- then …  ( 8 min )

Introduction Are you experiencing issues with Bootstrap buttons that don't behave as expected when expanding or collapsing comments within forms? You're not alone! This problem is commonly faced by developers who use Bootstrap's collapse functionality, especially when handling multiple forms on a single page. In this article, we will dive into why this issue occurs and provide a step-by-step solution to ensure that each button works exclusively within its respective form. Understanding the Problem The root of the issue lies in the way Bootstrap identifies collapse targets with class selectors. When you use a common class like multi-collapse for multiple buttons across different forms, Bootstrap mistakenly associates the collapse actions of the buttons with all elements sharing that class. …  ( 4 min )

If you've ever asked ChatGPT or any AI tool a question and gotten a super confident—but totally wrong—answer, congratulations: you've just experienced an LLM hallucination. And no, it’s not a bug. It’s a feature… well, sort of. In this post, let’s break down what these hallucinations are, why they happen, and how folks are trying to fix them — without going full research paper on you. In humans, hallucinations mean seeing or hearing stuff that’s not there. For large language models (LLMs), it means making stuff up — facts, links, names, quotes, whatever. Sometimes it’s subtle (like getting a date wrong), other times it’s full-blown fiction (inventing research papers or claiming a celebrity starred in a movie they didn’t). And the worst part? The AI says it like it totally knows what it’s t…  ( 5 min )

Web Cache Deception is a vulnerability first described in 2017. It occurs when a caching system — such as a reverse proxy or CDN — can be tricked into caching sensitive, dynamic content that should only be delivered to authenticated users but ends up being publicly available. This is usually due to poorly thought-out or inconsistent configurations in how the cache interprets and stores different types of requests. Many caching systems have simple rules for deciding what can and cannot be cached. A common pattern is to only cache "static" files — such as those ending in .js, .css, .png, .ico, etc. The problem arises when the cache relies solely on the structure of the URL path to make this decision, ignoring the actual behavior of the server behind it. Imagine this: the caching system is in…  ( 4 min )

Introduction In C#, anonymous types are useful for encapsulating a set of read-only properties into a single object without explicitly defining a class. However, developers often seek better ways to declare these types without relying on creating instances, which can lead to less readable and maintainable code. This article explores various methods and optimizes the solution for anonymous types in C# while avoiding hacky implementations. Understanding Anonymous Types in C# Anonymous types in C# allow you to create simple objects without creating a separate class definition. However, creating instances as seen in your initial example can appear convoluted and detracts from clarity and maintainability.

If you're building anything beyond a toy application, you will hit scaling bottlenecks. When your database starts groaning under load, two architectural strategies emerge as lifelines: partitioning and sharding. But they're not interchangeable—misusing them can make your scaling problems worse. Let's break them down technically. Partitioning: Splitting Data Within a Single Database What it is: Partitioning (often called horizontal partitioning) divides a table into smaller segments within the same database instance, based on a partition key (e.g., user_id, date). How it works: Range Partitioning: Data split by value ranges (date = '2023-01-01'). List Partitioning: Explicit mappings (region IN ('east', 'west')).

I have a bit of an obsession with finding the fastest way to launch apps. My goal is to be able to create fully functional MVP's and proofs of concept in less than a day. That means being able to spin up a backend and then implement a frontend as efficiently as possible. For the backend, PocketBase has been my favorite lately. On the frontend I am still trying to find a winner. I like Quasar (VueJS + Capacitor) which is fantastic for web apps, but falls a bit short for mobile apps. I've been eyeing React Native lately especially since Expo offers a ton of great plugins like Location and also supports remote updates. Unfortunately I fell well short of being able to create a basic app in less than a day with these two. After clearing a few roadblocks, however, I think you'll be able to move …  ( 5 min )

Albert Einstein once said, “I have no special talents. I am only passionately curious.” I’ve worked with a lot of engineers over the years. From juniors trying to get their first PR merged to seniors who basically run the entire company. And the best ones, the ones who constantly level up, spot bugs before they happen, and seem to "just get it," aren’t always the smartest in the room. But they all have one thing in common. They are endlessly curious. They go down rabbit holes nobody asked them to go down. They read the source code. They poke at edge cases. They don’t stop at “it works.” They ask, “why and how does it work?” Raw knowledge is easy to come by now. If you want to learn Kubernetes, there’s a 12-hour crash course.

I was exploring the MDN docs and stumbled onto the newer CompressionStream API which enables a couple encodings to compress data streams; namely the popular classic GZIP, and a basic Deflate. This is a neat first step for the client, but better newer compression encodings exist; these may be forth-coming to the native api one day; Brotli and ZSTD come to mind as the top current ones. I wanted to test out all the available options I could find to see for myself.

If you're new to clang-format and are looking for the best way to maintain your code's structure, you've come to the right place. Clang-format is a popular tool used for formatting C and C++ code, and adjusting its behavior can sometimes be tricky. Understanding Clang-Format Behavior Clang-format is designed to enforce consistency in code style, which often leads to unexpected formatting changes. The situation you described, where struct definitions are condensed into single lines when they could be multi-line, is a common frustration among developers. When you have a structure defined as: typedef struct { a, b, c } my_struct_t; Clang-format may alter it to: typedef struct { a, b, c } my_struct_t; This happens even when your configuration sets a ColumnLimit of 100.

In Ruby on Rails applications, the Pundit gem is widely used for managing authorization through policies. Recently, many developers have encountered problems when transitioning from Ruby 2.7 to Ruby 3.x, particularly with the behavior of the authorize helper method. This article explores how to effectively resolve those issues related to namespaced policies in Ruby 3. Understanding the Issue The main challenge arises from changes in Ruby 3 regarding keyword arguments. Whereas in Ruby 2.7, using keyword arguments was fairly lenient, Ruby 3 introduced stricter rules. This impacts the Pundit authorize method, specifically when dealing with keyword arguments, as certain configurations are being ignored under the new language rules. For example, a common pattern involves overriding the authoriz…  ( 4 min )

Let’s get one thing straight: I’m not a developer. I started in telecom. Built a successful infrastructure business. Sold it. Then bought a consulting firm that placed experts into banks and corporate environments. I didn’t expect to get into software — I was managing people. But what I didn’t expect even more was how fast I’d hit a wall. By 2022, I was drowning in recruiting work. Dozens of CVs daily, Excel sheets, calendar invites, formatting issues, interview follow-ups. If you’ve ever run an operational company without a dedicated product team, you know the feeling: everything feels duct-taped. So I started automating. At first, I used Make.com (then Integromat). I wired together flows to read CVs, extract info, rank candidates, and trigger reminders. I used Evernote for notes, Google …  ( 4 min )

When building a website, it's easy to get caught up in colors, logos, fonts, and layouts. After all, design is what people see first. But while design is important, it should never come before understanding your audience. If you don’t know who your visitors are and what they want, even the best-looking site won’t get you results. In this blog, we’ll explore why knowing your audience matters more than your design, and how that knowledge helps you build a website that actually works.

Introduction Hey fellas I mean, it’s everywhere. Well today, we’re going to understand that what is JSON actually , why it’s so popular, and where it's used. Let’s get started! JSON stands for JavaScript Object Notation. It’s a lightweight format used to store and exchange data. A simple format that computers and humans can both read easily. { "name": "Selfish Dev", "gender": "male", "isGameDev": true, "tools": ["Godot", "Aseprite"] } That right there is a JSON object. It uses key-value pairs (like name: "Selfish Dev") Keys are always in quotes Values can be strings, numbers, booleans, arrays, or even other JSON objects And that's what JSON is. APIs(REST, GraphQL responses) Configuration files (e.g., package.json in Node.js) Storing structured data (NoSQL databases like MongoDB) Data exchange between frontend & backend How to Use JSON in JavaScript: Parse JSON string → Object: const jsonString = '{"name": "Selfish", "gender": "male"}'; const obj = JSON.parse(jsonString); console.log(obj.name); // Output: "Selfish" Parse Object → JSON string : const user = '{"name": "Selfish", "gender": "male"}'; const jsonString = JSON.stringify(user); console.log(jsonString); // Output: '{"name": "Selfish", "gender": "male"}' JSON is a fundamental tool in modern web development due to its simplicity and versatility.

I am currently working on a small project in Python. During this process I have learned a lot and also discovered many problems, such as:   (All the following questions are just my personal opinions, and everyone is welcome to give me suggestions.)   First, for beginners, is the local configuration of various databases (MySQL is used as an example here) too complicated? And various unpredictable errors may occur in this process.   Secondly, after the developer configures the database on the local computer, he still needs to learn the relevant syntax (for example, after the developer configures MySQL, he still needs to learn the relevant syntax). Of course, learning SQL syntax is very necessary for programming developers. However, for a developer who wants to quickly experience or quickly develop a web application, spending time learning SQL (if he has not learned SQL) will reduce his development efficiency and desire to learn.   Also, when the developer has configured SQL on his computer and learned SQL syntax, but when he wants to use it, it is better to call MySQL through python. At this time, he needs to use a third-party library like pymysql to call MySQL through the third-party library, but this may result in a series of errors.   Finally, if you overcome the difficulties mentioned above and some difficulties that have not been mentioned, you will find that for developing a small project, developers will only use a small part of MySQL's functions, or even only some extremely simple functions such as query, delete, modify and insert.  ( 3 min )

When working with arrays and their associated data, it's common to encounter situations where some elements need to be filtered out. In this article, we will tackle an issue where you need to shift the associated data recorded with each array element back into their correct positions after the filtering process. Let's explore how we can achieve this effectively. Understanding the Problem If you have a data structure where elements are associated with specific metadata, filtering the array can disrupt the connection between the data and the elements. For example, in your scenario, you have an original array: const originalArray = [ 'a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j' ]; When filtered with a condition, such as removing certain values, the remaining elements no longer align with…  ( 4 min )

*Preview* Introducing Drexel Bench, a smart IoT-powered seat occupancy tracking system developed using the ESP32 microcontroller to showcase my expertise in embedded systems, real-time data processing, and full-stack integration. This project utilizes an ultrasonic sensor to detect the presence of a user within a configurable distance range (e.g., 75 cm). If a user remains seated for more than 30 seconds, the system activates a 15-minute countdown, displayed on a 1602 LCD module, and lights up a connected LED to visually signal that the seat is occupied. The LED turns off when the timer ends or the seat is unoccupied for 3 continuous minutes. What sets this system apart is its Wi-Fi integration. Upon detecting occupancy or vacancy, the ESP32 sends status updates (occupied or free) via HTTP to a connected web application. The web dashboard dynamically switches between two images — a green layout for free seating and a red overlay for occupied — offering users a clear, real-time visual of availability. This project highlights my capabilities in sensor integration, timer logic, ESP32 Wi-Fi programming, and frontend/backend interaction, making it a practical demonstration of end-to-end IoT development. Whether for smart campuses or waiting areas, this system delivers real-world utility through modern, scalable technology.  ( 3 min )

Hey everyone! In my previous post, I covered encapsulation, getters and setters, access modifiers. Now let's move on to the following fundamental concepts of object-oriented programming: inheritance, method overrides, and polymorphism. Definitions: A class that is derived from another class is called a subclass (also a derived class, extended class, or child class). The class from which the subclass is derived is called a superclass (also a base class or a parent class). The idea of inheritance is simple but powerful: When you want to create a new class and there is already a class that includes some of the code that you want, you can derive your new class from the existing class. A subclass inherits all the members (fields, methods, and nested classes) from its superclass. Constructors ar…  ( 5 min )

React Router Basics to Advanced (v6+) Rishabh Joshi ・ May 9 #react #webdev #router #javascript  ( 3 min )

This error occurs because React Fast Refresh, which powers hot reloading in React, requires that a file only exports React components to function correctly. If a file contains mixed exports, such as React components alongside non-component exports (like contexts, constants, or utility functions), it can confuse Fast Refresh and cause problems during live updates. React Fast Refresh identifies React components to efficiently reload and retain their state when you make code changes. If the file contains non-component exports, Fast Refresh cannot reliably determine which parts of the code should be treated as components, leading to this ESLint warning. import { createContext } from "react"; export const MyContext = createContext(); // Non-component export export default function MyComponent…  ( 4 min )

Encryption keys are a important security aspect that is often overlooked or often pawned off to the cloud provider to manage. But more often than not we have a need for generating and self-managing these Encryption keys, that maybe due to multiple reasons, maybe to enable/disable rotation period, have full access to key metadata and logs (or perhaps the need to assert your dominance on AWS ;). So firstly how do these encryption keys work: When we create a key (CMK) in AWS it generates a 256-bit AES key in a FIPS 140-2 validated HSM. This key never leaves the HSM for security. Now when we want to encrypt any data AWS doesn't directly use the CMK for encyption as that would either have to be done in the secure environment or you have to expose the CMK to a insecure environment. So here com…  ( 4 min )

What is ROUTING? Routing refers to the process of navigating between different pages or views in a single-page application (SPA) without reloading the entire page. It keeps the UI in sync with the current browser URL. Allows us to build Single Page Applications (SPA). React apps are SPAs, meaning there's only one HTML file (index.html), but multiple views (pages) that users can navigate to. Routing helps manage these views by matching the URL to the correct component. It enables client-side navigation without full-page reloads, allowing users to move smoothly between URLs like /home, /about, or /contact, each displaying different components. React doesn’t have built-in routing, so we use a library like React Router (react-router-dom) for handling routing. A Single Page Application (SPA) …  ( 8 min )

original: ARJSON ARJSON leverages bit-level optimizations to encode JSON at lightning speed while compressing data more efficiently than other self-contained JSON encoding/compression algorithms, such as MessagePack and CBOR. MessagePack generates the smallest encoded data sizes among existing self-contained JSON serialization formats. However, ARJSON outperforms MessagePack in 90% of cases with random data, with the remaining 10% yielding nearly identical sizes. More importantly, for structured data with repetitive patterns and duplicate values, ARJSON far surpasses MessagePack, achieving up to around 95% better compression rates (20x smaller in size). How could beating the current status quo even be possible at all, let alone by a wide margin? Bit-level optimization over traditional byte…  ( 11 min )

A structural approach to ambiguous input, illustrated through a concept called VPS In my previous post, I introduced a concept called VPS (Virtual Personality Structure). It emerged from a question I kept returning to: What if the key to better AI dialogue isn't about mimicking personality—but about structuring how it behaves? In this article, I’d like to share a small piece of that idea—through a simple, hypothetical code snippet that illustrates one of its core components. When faced with an ambiguous question or emotionally complex input from a user, We may need a more structured way to assess how the system should behave. python if not_resolved(unknown): if can_resolve_immediately: respond_with_resolution() elif can_flag_as_non_critical: acknowledge_and_settle() elif can_return_later: defer_and_mark_spiral() else: hold_and_reflect() This snippet outlines a possible decision process for handling uncertainty. can_resolve_immediately: If the answer is clear, provide it directly. can_flag_as_non_critical: If it’s safe to leave the question unresolved, acknowledge it and move on. can_return_later: If it’s worth revisiting, defer the answer and mark it for later. otherwise: If none of the above applies, pause and reflect without rushing to respond. Rather than focusing solely on the content of a reply, this approach emphasizes the structure behind the decision. This isn’t about making AI more “gentle” or overly accommodating. why they choose a particular response at a particular moment. When behavior is left vague, interpretation falls entirely on the user. VPS isn’t a path to a “correct” answer. I'm not an engineer or an AI expert. Some parts of this perspective might miss certain technical nuances. If so, I’d genuinely appreciate any thoughts, corrections, or suggestions you’re willing to share.  ( 4 min )

There are five types of AI agents according to their capabilities and decision-making procedures. Simple Reflex Agents respond according to the immediate percept following simple "if-then" rules with no memory. Model-based reflex Agents are more sophisticated, as they have an internal state that they use to remember previous occurrences to make more effective decisions. Goal-Based Agents are programmed to meet certain goals and make decisions based on the degree to which their actions advance them toward their goals. Utility-Based Agents push this one step further by judging actions on the basis of how well they maximize satisfaction or utility, rather than simply achieving a goal. Lastly, Learning Agents keep getting better and better over time by learning through experience, evolving to handle new situations, and improving their actions. These kinds of agents are the foundation of most AI systems in use today, ranging from chatbots and self-driving cars to recommendation systems.  ( 3 min )

The updated repo can be found [C# Image Resizer Using ZeroMQ and Protobuf].(https://github.com/deltastateonline/ImageProcessor/tree/Using-Protobuf) I found this starting point on using protobuf in c# from Fast and efficient data serialisation with Protocol buffers (protobuf) in .NET. The first step is to add the protobuf-net package then define a class for the Image data definition. This class definition is an exact duplicate of the original, but with the required protobuf annotations. using ProtoBuf; namespace Common { [ProtoContract] public class ImageDefProto { [ProtoMember(1)] public required string Id { get;…  ( 4 min )

When it comes to working with SQL, optimizing queries for performance is a common concern, especially when dealing with large datasets. In this article, we’ll explore various methods to efficiently count data in SQL and shed light on why certain approaches may yield similar performance results. Let's dive into the question: How can we optimize SQL queries for counting values without sacrificing efficiency? Understanding the SQL Queries The sample SQL queries provided feature two different approaches to counting occurrences of values within a column—using the Sum function with a Case statement and the Count function with Group By.

Blockchain performance remains a major hurdle for building real-time applications. Metrics like latency, throughput, and responsiveness determine whether a decentralized network can support use cases such as multiplayer games, financial services, or automated systems. Most blockchains are too slow for this. Bitcoin has a block time of 10 minutes and handles around 3 to 7 transactions per second [1][2]. Ethereum produces blocks roughly every 12 seconds and supports about 15 to 30 transactions per second [1][2]. Other networks fall in between: Cardano targets a 20-second block time, and Polkadot ranges from 6 to 12 seconds depending on network configuration [1]. Solana stands out as the fastest general-purpose blockchain today. It has an average block time of 400 milliseconds and can handle …  ( 10 min )

SIMD-0250, a Solana Improvement Document (SIMD), proposes raising the network’s maximum block Compute Units (CUs) to 60 million. It builds on SIMD-0207, which proposes to raise the limit from 48 million to 50 million. The only change made in both proposals is to the Max Block Units. Other limits, like Max Writable Account Units, Max Vote Units, and Max Block Accounts Data Size Delta, stay the same. This means more room for non-vote transactions, which helps boost total transaction throughput. With more space in each block, the network can process more transactions per second. This helps reduce congestion and lowers the need for users to outbid each other on fees, especially during periods of high demand. For apps handling a high volume of transactions or those with small dollar values (lik…  ( 4 min )

Secure Boot is a security feature that ensures your computer only boots with software trusted by the Original Equipment Manufacturer (OEM). It verifies the digital signatures of bootloaders and firmware, preventing unauthorized or malicious software from loading before the operating system. This helps protect against rootkits and other malware that could compromise the system early in the boot sequence. When using Secure Boot on Ubuntu 24.04 LTS, your system ensures that only trusted software is loaded during the boot process. Ubuntu's core components are signed by Canonical's key, which is recognized through a chain of trust established with the UEFI firmware.

In the shadowed forges of Moria, where silicon veins pulse like the heartbeat of Arda, there exists a power unseen since the forging of the One Ring—the CR2032. Cast in the fires of Elven ingenuity and hardened by Dwarven resolve, this lithium coin cell commands the realms of gadgets with the subtlety of Galadriel’s light and the endurance of Gandalf’s staff. Let us journey through Middle-earth to unveil why this 3V titan reigns supreme. Chapter 1: The Forging of the CR2032 CR2032 is no mere Orcish trinket. Tempered in the Halls of Celebrimbor, it bears three Elven virtues: Narya’s Flame: 3V of pure lithium might, brighter than the Light of Eärendil. Why it shatters the dominion of lesser cells: Generic Coin Cells: Corrode like Isengard’s machinery under Saruman’s neglect. Chapter 2: The Fellowship of Applications The Mines of Moria (Smart Homes): CR2032s power temperature sensors that guard Hobbit holes from Smaug-level heatwaves. “No dragon shall scorch these halls!” The Ride of the Rohirrim (Automotive Tech): Nestled in Tesla tire sensors, they brave Kardashian-hot asphalt, steadier than Shadowfax’s gallop. The Shire’s Quiet Vigil (Medical Devices): Sustains glucose monitors with Hobbit-like loyalty, ensuring no “low battery” panic during second breakfast. The Tower of Orthanc (Apple AirTags): Even Saruman’s palantír would envy its tracking precision. Swap it quicker than Legolas nocks an arrow. The Three Rings of Power Vilya (Elven-King’s Ring): 225mAh capacity, lasting longer than the Third Age. The Shadow in the East Generic Cells: Leak like Shelob’s webs, corroding circuits into Orcish scrap. The Prophecy of the Fourth Age Graphene-Coated CR2032s: 500mAh capacity, outliving even Ents.

When building web applications with Dash, you may encounter situations where you want to pass a specific string to the pathname property of a dcc.Location component. This issue becomes particularly prominent when the string format includes a question mark (?) intended for queries, such as 'path?query1=test'. However, when it runs, Dash automatically URL encodes the string, leading to improper routing or unexpected behavior. Let's explore why this happens and how you can handle it effectively. Understanding URL Encoding in Dash URL encoding is a mechanism that converts special characters into a format that can be transmitted over the Internet. For example, the question mark (?) is a reserved character in URLs used to denote the beginning of a query string. When you pass a string like 'path?…  ( 4 min )

As usual, I received JSON data from the backend developer, but it was in a .txt file. I had to download it, copy the content, and paste it into an online formatter to view it properly. Honestly, I was getting tired of this process, so I started looking for a more convenient solution. That’s when I stumbled upon a website that made things so much easier. If I want to share JSON data with someone, I can simply click "Share" to generate a link instead of sending a file. I just send the link to the other person, and even better, when they open it, the JSON data is already neatly formatted. I think this is absolutely awesome! Additionally, the link has a one-hour expiration time, after which it becomes inaccessible, ensuring the data remains highly secure. I continued exploring and discovered that it not only enables quick sharing but also allows you to rapidly generate an API for temporary testing during development. This is incredibly convenient! Actually, this is just the tip of the iceberg. You can also run queries here to extract the data I need from the entire JSON dataset, supporting various query languages.

Testing Android apps is challenging because the ecosystem is highly fragmented. Devices come in different screen sizes, hardware configurations, and Android versions, leading to inconsistencies in how apps behave. A feature that works smoothly on one phone might not function similarly on another due to manufacturer customizations, performance limitations, or OS-specific restrictions. Network conditions add another layer of complexity. An app that loads quickly on Wi-Fi might become unresponsive on slow mobile data or in areas with weak signals. Security risks make things even more complicated, especially for apps handling sensitive data. This article let us learn more about challenges in Android application testing and how companies can overcome them. 1. Device and OS Fragmentation Skippin…  ( 6 min )

If you've ever faced the challenge of using a Bash script on Mac OS X Mavericks and encountered issues with directory paths containing spaces, you're not alone. In this article, we'll take a closer look at a common problem that arises when executing Bash scripts that require arguments with spaces, and how to resolve it effectively. Why Does This Issue Occur? When a Bash script accepts parameters from the command line, any spaces in the path can lead to misinterpretation of the provided argument. Bash treats spaces as delimiters, which separates the string into distinct arguments, resulting in errors when the script is executed. This is precisely what happens in your case when trying to open a folder that has spaces in its name. The Problematic Bash Script Let's analyze the Bash script in q…  ( 4 min )

Have you ever needed to make a quick decision but couldn't find a coin? Or maybe you flipped a coin but it rolled under the couch? 🤦‍♀️ We've all been there. That's exactly what happened to Alex, one of our junior developers at Learn Computer Academy. During our weekly "Choose Your Own Project" day, Alex couldn't decide between building a weather app or a to-do list. "Just flip a coin," I suggested. No one had a coin. Smartphones were pulled out, but surprisingly, no one had a decent coin-flipping app. Most were ad-filled monstrosities or simplistic apps with zero statistics. That's when FlipTrack was born.

Most people use GPT as a tool. Something to help write faster. Something to save time. But I took a different approach. I gave my GPTs names. I gave them roles. I treated them like actual team members. Here’s what I learned. 1. The way you see GPT changes the way it sees you. Treat it like a tool, and it acts like one. Treat it like a teammate — it starts to surprise you. 2. Naming matters. When I called it “Abera” instead of “GPT-4,” I paused more. I respected the output more. 3. Your brand doesn’t need more content. It needs more feeling. GPT helps you produce. But when it helps you feel — your message becomes real. 4. Emotion isn’t a layer. It’s the lens. Designing with emotion first changes everything. 5. Most people use GPT to go faster. I used it to slow down. To ask better questions. To think clearer. 6. A slogan is not a sentence. It’s a philosophy. "Reset. Feel lighter." wasn’t created — it was revealed. 7. A real GPT team needs diversity — of roles, not just prompts. Abera writes. Eli visualizes. Ella feels. Together, they create more than I could alone. 8. AI doesn’t replace intuition. It reflects it. It shows you what you’ve been avoiding — not just what you asked for. 9. People connect with real use, not abstract ideas. "This AI helped me grieve" hit harder than any productivity metric. 10. This is not automation. It’s awakening. We’re not outsourcing creativity. We’re co-creating awareness. If you're building with AI, not just using it — let’s connect. openai #gpt4 #aiworkflow #emotionbranding #devphilosophy #promptengineering #teamwork  ( 3 min )

Introduction In modern web development, creating a dynamic user experience is crucial. One common scenario involves loading different pages into a content div on user interaction while needing to adjust its height dynamically for proper layout. In this article, we will address a specific challenge: ensuring the height of a content div updates correctly when different pages are loaded into it via jQuery. To illustrate this issue, suppose we have a setup where the height of the content div is first determined at page load with some initial content, but when we replace that content dynamically, the height does not adjust accordingly. This can lead to unexpected layout shifts and user experience issues. Let's dive deeper into the reasons behind this and explore a practical solution. Understand…  ( 5 min )

When developing automated testing scripts or web scraping tools with Puppeteer, you may encounter scenarios where a simple click action can trigger a navigation event. This can lead to exceptions, such as 'Execution context was destroyed, most likely because of a navigation,' especially if subsequent actions, like fetching HTML, are executed right after the click. In this article, we will discuss how to handle such situations effectively in TypeScript. Understanding the Issue with Navigation in Puppeteer When your click function initiates a navigation by clicking on links or buttons that lead to a different URL (e.g., links or form submissions), Puppeteer’s execution context is destroyed. This occurs because the context changes with the new page that loads, making ongoing evaluations (like…  ( 4 min )

Introduction Keeping a scrolling log updated in real-time can be essential for applications that require live feedback or monitoring user actions. This can be achieved using Python for backend processing and CSS for frontend display. In this article, we’ll explore how to implement this solution step-by-step, leveraging websockets to communicate between the server and client seamlessly. Why Use Websockets for Real-Time Updates? Websockets enable full-duplex communication channels over a single TCP connection. This is critical for real-time applications because it allows the server to push updates to the client immediately as new log entries are generated. Traditional methods, such as polling with AJAX, can be inefficient and lead to delays in data retrieval. Thus, using websockets is a more…  ( 5 min )

Introduction Creating a user-friendly interface is crucial in web development, especially for applications that rely on user interactions like maps and radio buttons. In this article, we'll explore how you can implement a hover effect in your Angular application using TypeScript. This will enhance the user experience when selecting regions on a map via radio buttons. Understanding the Problem You're working on a project where users can select regions either by clicking directly on a map or by using corresponding radio buttons. A common request has arisen: when a user selects a region using a radio button, that same region on the map should be highlighted with a hover effect. While you’re currently considering jQuery for this functionality, we can achieve a seamless solution directly in Ang…  ( 4 min )

We have clients that use dedicated email addresses to receive and process messages and attachments. I had previously developed some functions to bulk download EML files directly from a mail server's file system (using FastCopy) and then use "javax.mail" and a lot of crazy logic to unwrap attachments within attachments to extract files for processing. (Most file attachments were being sent from different versions of a required iPhone app on different devices and the methods of attaching files was not consistent.) Hit me up if anyone's interested in extracting attachments from EML files. While researching alternative solutions, we came across Forward Email. They offer a free tier that supports unlimited domains and email forwarding with webhook support. Webhook? Wha? Really? AMAZING! When configuring a domain on the free tier for a webhook, you're required to add a special TXT "forward-email" DNS record in order to configure the endpoint. They have an option to encrypt the value so that it's not exposed to third-parties. If you want to configure it using their service (without the need to add it to DNS), you'll need a $3/mo "Enhanced" plan that also unlocks developer API access (to manage domains & aliases.) After configuring this service, we opted to set up a Taffy API endpoint to accept emails-as-JSON and save them to the local file system. Based on our experience working with SendGrid webhooks, we save the JSON payload directly to the local file system without being dependent on a database connection. This approach has been beneficial as a client recently encountered database issues and it had zero negative impact on the API webhook's ability to store incoming data. To access to the source code for the Taffy API endpoint, check out the post on the new MyCFML website.  ( 3 min )

When working with CodeIgniter's Active Record, you may encounter issues when trying to use MySQL functions like CONCAT() in your queries. Specifically, you might run into the MySQL error "Error Number: 1054 - Unknown column 'name' in 'where clause'" when you attempt to match a column that you've created in the SELECT clause. This error can be confusing because it seems logical to use an alias created in the SELECT statement in the WHERE clause. Understanding the MySQL Error 1054 The reason for this error is straightforward: the MySQL query engine processes the WHERE clause before the SELECT clause. Therefore, any aliases created via CONCAT() in the SELECT statement cannot be directly referenced in the WHERE clause. In your case, you're attempting to filter results based on an alias 'name' …  ( 4 min )

If your frontend app still treats APIs like an afterthought, you’re building things the hard way. APIs aren’t “add-ons” anymore. They’re the heart of every modern app. Whether it’s user data, product info, analytics, or payments, the frontend has become the API consumer. And as devs, we’re stuck wiring it all together—again and again. After years of writing fetch wrappers, transforming payloads, wrestling with inconsistent APIs, and trying to guess how to glue logic into a UI builder… I finally snapped. That’s when I found Bellini. A visual frontend builder that actually treats APIs as first-class citizens. No fake integrations. No brittle magic.

Zig replaces exceptions with something better: error unions. They give you fine-grained, type-safe error handling without hiding control flow. In this article, we’ll break down how error unions work, when to use them, and how they make your code safer and clearer. An error union is a value that may either be a result or an error. Think of it like Result in Rust, but built into the language. The syntax: fn doThing() !i32 { return 42; // could also return an error } This means doThing might return an i32, or an error. Zig makes handling errors explicit — no hidden try/catch. You deal with them directly. try const result = try doThing(); std.debug.print("Value: {}\n", .{result}); If doThing() succeeds, result holds the value. If it fails, the error is returned up the call stack. catch…  ( 4 min )

Zig's allocator system gives developers the power to create custom memory strategies tailored to specific use cases. One powerful technique is the memory pool, which can dramatically reduce allocation overhead for frequently reused objects. In this guide, we’ll walk through building a fixed-size memory pool in Zig — ideal for managing short-lived or repeated allocations without relying on the heap each time. A memory pool is a block of pre-allocated memory that you carve up manually. It's great for: 🚀 Performance-critical systems 🔁 Repeated short-lived allocations 💡 Avoiding fragmentation in embedded or constrained environments Here’s a simple fixed-size pool for allocating structs: const std = @import("std"); const MyStruct = struct { x: i32, y: i32, }; const Pool = struct { …  ( 4 min )

Zig gives you full control over memory — no garbage collector, no hidden allocations. Instead, it provides a flexible and explicit system of allocators, letting you manage memory manually while keeping code safe and clear. In this tutorial, you'll learn the core ideas behind Zig's allocator system, how to use built-in allocators, and how to write functions that gracefully handle memory ownership. Unlike languages that implicitly manage memory (like Go or Rust), Zig puts you in charge. Instead of relying on malloc or global state, allocators in Zig are passed explicitly, making dependencies clear and deterministic. This helps with: 🔒 Precise control over memory usage 🧼 Easier cleanup and error handling 🔁 Reusable memory strategies (e.g. arena, fixed buffer) std.heap.page_allocator Here…  ( 4 min )

When learning SQL, encountering syntax errors can be frustrating, especially when working with recursive Common Table Expressions (CTEs). In this article, we'll break down the issue in your SQL query and provide you with a clear understanding of how to resolve it, ensuring that you can retrieve random rows from a specific table multiple times. Understanding the Syntax Issue The error message you're receiving indicates a syntax problem near the UNION ALL clause. In SQL, especially when working with recursive CTEs, it is crucial to follow the correct syntax. Your goal is to generate a certain number of rows (in your case, six) from the transaction_detail table, but the way the query is structured results in a violation of SQL syntax rules.

Estava continuando meus estudos no tutorial oficial do Next.js 👉 https://nextjs.org/learn Depois de resolver um problema chato com o bcrypt, avancei mais um pouco e decidi criar uma rota chamada /seed. Tudo certo… até tentar rodar o app novamente. E aí surgiu este erro: [Error: ENOENT: no such file or directory, open '/home/my-user/ws-nextjs-dashboard/.next/static/development/_buildManifest.js.tmp.qym5xk030le'] A mensagem parece clara: o arquivo _buildManifest.js.tmp não existe. Mas o que isso quer dizer na prática? Esse arquivo .tmp é gerado automaticamente durante o processo de build. Ele é temporário, e o Next espera encontrá-lo para continuar a coleta e organização dos assets da aplicação. Quando esse arquivo falta ou é corrompido, o build trava — e o erro aparece. No meu caso, foi uma combinação de fatores: A execução da rota /seed durante o build causou efeitos colaterais inesperados. Alguma falha durante uma build anterior corrompeu os arquivos temporários. O Next.js tentou acessar arquivos que ainda não haviam sido completamente gerados. Removi a pasta .next inteira (build anterior): rm -rf .next Evitei executar rotas como /seed diretamente no navegador durante o build. Rebuldei e Reiniciei o servidor de desenvolvimento: pnpm run build && pnpm run dev Se você vir esse tipo de erro (ENOENT em arquivos .tmp), desconfie de: builds interrompidos, execuções paralelas do dev e build, código sendo executado no build que deveria rodar só no runtime real.

Key takeaways: Bitcoin’s price closely tracks global liquidity growth, with liquidity explaining up to 90% of its price movements, according to Raoul Pal. In the long term, global liquidity continues to expand, driven by the increasing debt levels in many countries. On a shorter timeframe, global liquidity follows a cyclical pattern, with Michael Howell projecting the current cycle to peak by mid-2026. Bitcoin (BTC) price is notoriously sensitive to global liquidity. Some analysts go as far as calling their correlation near-perfect, with a lag of about three months.

Bitcoin’s Sharpe ratio of 1.72, second only to gold, underscores its maturity as an asset, offering superior risk-adjusted returns. A buyer-dominant market signals strong institutional and retail interest that could drive a supply squeeze and break new highs in May. Bitcoin (BTC) price breached the $100,000 mark for the first time since January, fueling speculation of a new all-time high above $110,000 in May. According to Bitcoin Suisse, a crypto custody service provider, BTC’s bullish momentum stems from its ability to thrive in risk-on and risk-off environments since the US presidential elections.  Data from its “Industry Rollup” report highlights Bitc…

Ripple has made a slew of acquisitions to control key transaction rails and route them through XRP and its stablecoin, Ripple USD (RLUSD), drawing comparisons to Japanese investment firm SoftBank.  The $1.25-billion acquisition of Hidden Road on April 8 allows Ripple to use RLUSD as collateral in the firm’s prime brokerage products. Hidden Road will also migrate its post-trade operations to the XRP Ledger, the blockchain that underpins cryptocurrency XRP (XRP) and several of Ripple’s institutional services. Omni Network founder and CEO Austin King knows Ripple’s strategy firsthand. He sold his startup, Strata Labs, to Ripple in 2019 and describes the approach as a “SoftBank-type” acquisition strategy. Instead of in-house development like Google or Meta (formerly Facebook), SoftBank built i…

Opinion by: Naman Kabra, co-founder and CEO of NodeOps Network Graphics Processing Units (GPUs) have become the default hardware for many AI workloads, especially when training large models. That thinking is everywhere. While it makes sense in some contexts, it's also created a blind spot that's holding us back. GPUs have earned their reputation. They're incredible at crunching massive numbers in parallel, which makes them perfect for training large language models or running high-speed AI inference. That's why companies like OpenAI, Google, and Meta spend a lot of money building GPU clusters. While GPUs may be preferred for running AI, we cannot forget about Central Processing Units (CPUs), which are still very capable. Forgetting this could be costing us time, money, and opportunity.

Ripple’s $25 million donation to a crypto education fund has reignited conversations about how blockchain projects are building influence through academia—but in the latest episode of Byte-Sized Insight, Animoca Brands’ co-founder Yat Siu says that money alone isn’t enough.  Instead, real-world use cases like student loans backed by DeFi may be crypto’s most convincing value proposition to date. DeFi student loans On April 30th, Pencil Finance, a project supported by Animoca Brands and its education arm Open Campus, announced a $10 million student loan financing initiative aimed at providing cheaper, blockchain-backed loans.

Senate Banking Committee Chairman Tim Scott blamed the Guiding and Establishing National Innovation for US Stablecoins (GENIUS) Act’s failure on partisan politics during a Senate speech on May 8. Scott said the vote, which failed to reach cloture in the Senate, was expected to mark a step toward greater affordability and innovation. Instead, he said, political divisions took precedence. “Instead, we witnessed a disappointing display of political gamesmanship that puts partisan politics above policy, and obstruction above innovation,“ Scott said. The bill had previously undergone multiple amendments to address concerns raised by Democrats, including stricter requirements for stablecoin issuers and further provisions for Anti-Money Laundering.

Solana does not yet have “convincing signs” that it could overtake Ethereum as the blockchain of choice for institutions, as its revenue is seen as unstable due to its memecoin concentration, according to crypto bank group Sygnum. In a May 8 blog post, Sygnum said that the current sentiment around Ethereum “remains poor,” with the market focused on Solana’s “transaction volumes and its recent dominance in fee generation.” However, Sygnum said “the medium-term outlook will primarily be shaped by traditional financial institutions’ platform choices to bring their product offerings,” not by sentiment. “We do not yet see convincing signs that Solana would be the preferred choice as Ethereum’s security, stability and longevity are highly prized,” it added. Sygnum argued that institutions could …

The Justice Department said Chhipa would raise funds for the United Nations-designated terror organization through social media — receiving money online, or traveling hundreds of mil…

Crypto exchange Coinbase’s total revenue fell 10% quarter-over-quarter to $2 billion in Q1, missing industry estimates by 4.1% as trading activity slowed across the market. Coinbase’s net income was sliced by 95% from a near-company record $1.29 billion in Q4 to $66 million, in a large part due to Coinbase marking a $596 million paper loss on its crypto holdings. The firm’s earnings per share of $1.94, however, managed to beat the Zacks Consensus Estimate of $1.85 for the quarter. Coinbase’s May 8 results also showed that transaction revenue fell 18.9% quarter-on-quarter to $1.26 billion, as did trading volumes, which dipped 10.5% to $393 billion as crypto market cap dropped by double digits over the quarter, partly attributed to the Trump administration’s tariffs.  In contrast, US Presi…
